                                   PROSPECTUS

                                9,900,000 Shares

                                FONAR CORPORATION

                                  Common Stock

     This prospectus will allow us to issue common stock to the owners of our 4%
convertible  debentures  due June  30,  2002,  purchase  warrants  and  callable
warrants if the owners elect to exercise  their  options to convert or exercise.
This  prospectus  will also  allow the owners to resell  the  shares.  Since the
owners  will be able to  exercise  their  rights up to June 30,  2002  under the
debentures,  up to May 24, 2006 under the  purchase  warrants  and up to May 24,
2004 under the callable warrants, the common stock may be issued over time. This
means

- -    we will  provide a  prospectus  supplement  as required to update  material
     information contained in this prospectus; and

- -    you should  read this  document  and any  prospectus  supplement  carefully
     before you invest.

- -    The  conversion  price for the  debentures  and the exercise  price for the
     purchase  warrants are fixed.  The proceeds we would  receive if the owners
     elect to buy the common  stock are shown  below.  Neither we nor the owners
     will  have to pay any  commissions  on  debenture  conversions  or  warrant
     exercises.

                            Maximum No.        Per Share         Maximum
         Security           of Shares             Price          Proceeds
         -----------        -----------        ---------        ----------

         Convertible         2,198,339           $2.047         $4,500,000
         Debenture

         Purchase              959,501           $1.801         $1,187,761
         Warrant

     The exercise  price for the callable  warrants will change at the beginning
of each calendar month and be equal to the average  closing bid price of Fonar's
common  stock  for  the  prior  calendar  month.  Assuming  for the  purpose  of
illustration that the callable warrants are exercised at $1.66 per share,  which
was the  closing  bid  price for the  common  stock on June 15,  2001,  we would
receive proceeds as shown below:

                            Maximum No.        Per Share         Maximum
         Security           of Shares             Price          Proceeds
         -----------        -----------        ---------        ----------

         Callable
         Warrants            2,000,000           $1.66          $3,320,000

     Even if the debentures  are not converted  because the market price for the
common  stock is less than the  conversion  price for the  debentures,  we would
still have the option of paying the debentures in common stock rather than cash.
In this case,  however,  the common stock would be valued at a much lower price,
at the lesser of a) 90% of the  average of the four  lowest  closing  bid prices
during the preceding calendar month or b) the average of the four lowest closing
bid prices during the  preceding  calendar  month less $0.125.  Assuming that we
were paying the $4.5 million  principal in  debentures  today  according to that
formula, the common stock required to be issued would be as follows:

                            Maximum No.        Per Share         Maximum
         Security           of Shares             Price          Proceeds
         -----------        -----------        ---------        ----------

         Convertible
         Debenture           3,435,115           $1.31          $4,500,000

     An  investment  in our common  stock is subject to a high level of risk and
you should  carefully  read and  consider  the risk  factors  described  in this
prospectus, see "RISK FACTORS".

     THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED BY THE SECURITIES
AND  EXCHANGE  COMMISSION  NOR HAS THE  COMMISSION  PASSED UPON THE  ACCURACY OR
ADEQUACY OF THIS PROSPECTUS.  ANY  REPRESENTATION  TO THE CONTRARY IS A CRIMINAL
OFFENSE.

     We expect to pay expenses in this offering of approximately $78,000.

     On June 15, 2001, the closing price for our common stock (Symbol: FONR) was
$1.67 per share, as reported by Nasdaq. Our common stock is traded on the Nasdaq
SmallCap Market.

                              ABOUT THIS PROSPECTUS

     This prospectus is part of a registration  statement that we filed with the
Securities and Exchange Commission using a "shelf" registration  process.  Under
this shelf  process,  we may from time to time issue any number of the shares of
our common stock upon the  conversion  of the  debentures or the exercise of the
warrants up to a total of 9,900,000 shares.

     The number of shares being registered,  by the terms of the agreements with
the Tail  Wind Fund is two times  the  number  of  shares  necessary  to pay the
debentures at the lower of the market price, as computed under the agreements or
conversion price, plus the number of shares underlying the warrants.

     Periodically,  we expect to provide a prospectus  supplement that will add,
update or change information contained in this prospectus.  You should read both

                             ABOUT FONAR CORPORATION

     At, Fonar we design,  manufacture  and market  magnetic  resonance  imaging
(MRI)  scanners.  MRI scanners use magnetic fields to generate images of organs,
bones and tissue  inside the human body.  The MRI scanner uses a magnetic  field
which causes the hydrogen  atoms in tissue to align.  When the magnetic force is
withdrawn,  the atoms fall out of alignment  emitting  radio signals as they do.
The speed at which the atoms fall out of  alignment,  or  "relaxation  time" and
radio signals vary  depending on the type of tissue and whether any pathology is
present.  The radio signals provide the data from which the scanner's  computers
generate  an image of the body part  being  scanned.  Our  address is 110 Marcus
Drive,  Melville,  New York 11747,  our telephone number there is (631) 694-2929
and our Internet address is http://www.fonar.com.

     Fonar  offers  the  following  MRI  scanners:  the  Stand-Up,  also  called
Indomitable  (TM),  QUAD (TM),  Fonar-360  (TM) and Echo (TM). The Pinnacle (TM)
MRI, a  work-in-progress,  recently  received FDA clearance to market on June 6,
2001.

     The  Stand-Up  allows  patients to be scanned  while  standing,  sitting or
reclining.  We believe  that the  Stand-Up is the first and  presently  only MRI
scanner in which this is possible.  This means that any  abnormality  or injury,
such as a slipped  disc,  will be able to be scanned  under full  weight-bearing
conditions,  or,  more  often than not,  in the  position  in which the  patient
experiences  pain.  An elevator  built into the floor  brings the patient to the
desired  height in the scanner.  An adjustable bed allows the patients to stand,
sit or lie on their backs, sides or stomachs, at any angle.

     In the future,  the Stand-Up  may also be useful for MRI directed  surgical
procedures and could be particularly  useful in trauma centers where a quick MRI
screening  within the first critical hour of treatment would greatly improve the
patient's chances for survival and complete recovery.

     The Fonar 360 is an enlarged room sized magnet in which the floor,  ceiling
and walls of the room are part of the magnet frame.  Consequently,  this scanner
allows 360 degree access to the patient.  Physicians and family members are able
to  actually  enter the  scanner  and  approach  the  patient.  The Fonar 360 is
presently  marketed as a diagnostic  scanner and is sometimes referred to as the
Open Sky MRI. The walls can be decorated  with  panoramic  murals and the entire
scan room can be decorated to be incorporated into the pictured landscape.

     In the future,  we may also further develop the Fonar 360 to function as an
operating  room.  We  sometimes  refer to this  version  of the Fonar 360 as the
OR-360.  The room sized magnet and 360 degree access to the patient would permit
surgical teams to walk into the magnet and perform surgery on the patient inside
the magnet.  The MRI image could be obtained during surgery to guide the surgeon
in the surgery.  Surgical instruments,  needles,  catheters,  endoscopes and the
like could be  introduced  directly  into the  patient's  body and guided to the
right location by means of the MRI image. For example, chemotherapy or radiation
in a cancer  case  could be  delivered  directly  to the  malignant  tumor.  The
challenges  in  converting  the  Fonar-360 to an actual  operating  room include
designing  instruments  and  support  equipment  which can be used in a magnetic
field and conforming the OR-360 to operating room standards for the surgeries in
question.

     The QUAD  scanner is open on four  sides,  thereby  allowing  access to the
scanning  area from four  sides.  We believe the QUAD (TM) 12000 MRI scanner was
the first  "open" MRI scanner  with a high field  magnet.  The QUAD (TM) 7000 is
similar in design to the QUAD 12000 but uses a smaller lower field magnet.

     We are also  developing  the  "Pinnacle"  (TM)  which is a  superconductive
version of our open iron frame  magnet.  The Pinnacle  received FDA clearance on
June 6, 2001.

     Fonar also offers a low cost, low field open MRI scanner, the Echo (TM).

     In addition to manufacturing MRI scanning systems,  we formed a subsidiary,
Health Management  Corporation of America, which we sometimes call HMCA, in 1997
to engage in the business of managing imaging  facilities and medical practices.
HMCA provides and supervises the non-medical  personnel for the clients at their
sites.  At HMCA we also  provide our clients  centralized  billing,  collection,
marketing,  advertising,  accounting  and  financial  services.  We also provide
office  equipment  and  furnishing,  consumable  supplies  and in some cases the
office  space  used by our  clients.  Almost all of HMCA's  client  professional
corporations are owned by Fonar's founder,  President and Chairman of the Board,
Dr. Raymond V. Damadian.

Risk Factors...............An  investment  in our stock is high risk You  should
     carefully  consider the risk  factors in this  prospectus  before  deciding
     whether to purchase the shares offered. See "Risk Factors."

     This summary is qualified in its entirety by the more detailed  information
appearing elsewhere in the prospectus.


                                  RISK FACTORS

     An investment in Fonar is highly  speculative  and subject to a high degree
of risk. Therefore,  you should carefully consider the risks discussed below and
other  information  contained in this  prospectus  before  deciding to invest in
shares of our common stock.

1. We have and continue to experience significant losses.

     For the fiscal years ended June 30, 2000 and June 30, 1999, we  experienced
net losses of $10.96 million and $14.22 million  respectively  and net operating
losses of $16.43  million and $15.61 million  respectively.  For the nine months
ended March 31, 2001, we experienced a net loss of $9.7 million and an operating
loss of $10.8  million.  We have been  able to fund our  losses to date from the
$128.7 million judgment,  net $77.2 million after attorney's fees, received from
General Electric  Company in 1997 for patent  infringement and from other patent
litigation settlements with other competitors, the terms of which agreements are
required to be kept  confidential.  As of March 31, 2001,  however,  our balance
sheet shows  approximately  $10.3 million in cash or cash  equivalents  and $7.6
million in marketable  securities  out of total current assets of $40.1 million.
We  believe  that we will be able to  reverse  our  operating  losses  with  the
introduction into the marketplace of our new MRI scanners and from the operating
income generated by our subsidiary HMCA. HMCA operating income was $3.12 million
in fiscal 1999, $2.48 million in fiscal 2000 and $2.2 million for the first nine
months of fiscal 2001. There can be no assurance,  however,  that we can reverse
our operating losses.

2. Fonar is dependant on the success of its new products to become profitable.

     Our ability to generate future operating profits will depend on our ability
to market and sell our new lines of MRI products.  The Stand-Up MRI, also called
"Indomitable(TM),  Fonar  360(TM)  and Echo  scanners  have  all  been  recently
introduced  into the market.  Although we are  optimistic  that these  scanners'
features will make them competitive,  there can be no assurance as to the degree
or timing of market  acceptance  of these  products.  Revenues from the sales of
QUAD(TM)  scanners,  introduced  in 1995,  have not been  sufficient  to date to
generate  operating  profits.  The  product  we  are  currently  promoting  most
vigorously  is the  Stand-Up  MRI.  We  believe  the  Stand-Up  MRI is the  most
promising  because it enable scans to be performed on patients in weight bearing
positions,  such as sitting or  standing.  The  market for the  Stand-Up,  which
received FDA clearance in October 2000, is still largely untested. The following
chart shows the revenues  attributable to each model between October 1, 2000 and
March 31, 2001.  Please note that we recognize the revenue on scanner sales on a
percentage  of  completion  basis.  This means we book  revenue  not as money is
received  or sales are made,  but as the  scanner  is built.  Consequently,  the
revenues for a fiscal period do not  necessarily  relate to the orders placed in
that period.

                Model                    Revenues Recognized
                ---------                -------------------
                Stand-Up                    $   990,700
                Fonar 360                             0
                QUAD                        $ 1,798,645
                Echo                        $   328,950

3. We must  compete in a highly  competitive  market  against  competitors  with
greater financial resources than we have.

     The medical equipment  industry is highly  competitive and characterized by
rapidly changing  technology and extensive research and development.  The market
demand for a continuing  supply of new and improved products requires that we be
engaged  continuously  in research and  development.  New products  also require
continuous retooling or at least modifications to our manufacturing  facilities,
and our sales and marketing force must  continuously  adjust to new products and
product  features.  This is highly  expensive and companies  with  substantially
greater  financial  resources  than we have engage in the  marketing of magnetic
resonance   imaging   scanners  which  compete  with  the  Company's   scanners.
Competitors include large,  multinational  companies or their affiliates such as
General Electric  Company,  Siemens A.G.,  Picker  International,  Philips N.V.,
Toshiba Corporation,  Hitachi Corporation and Shimadzu Corporation. There can be
no assurance  that Fonar's  products will be able to  successfully  compete with
products of its competitors.

4. The  success  of some of the  businesses  purchased  by HMCA  depends  on the
continued employment of the former owners of those businesses.

     The businesses acquired by HMCA are essentially service organizations whose
continued  success  depends  on  retaining  and  developing   existing  business
relationships.  These  relationships are often heavily dependant on the personal
efforts of key persons in the acquired company or medical  practices  managed by
the  acquired  company.  HMCA has  sought to retain  these  key  people  through
employment agreements which include both noncompetition  covenants and financial
incentives.  Nevertheless,  there can be no assurance that these key people will
remain as employees or produce results sufficient to make the acquired companies
profitable.

5. HMCA'S  profitability  depends on its ability to successfully perform billing
and collection services for its clients.

     HMCA performs billing and collection services for the medical practices and
MRI facilities it manages.  The viability of HMCA's clients and their ability to
remit  management fees to HMCA depends on HMCA's ability to collect the clients'
receivables.  Collectibility of these  receivables can be adversely  affected by
the  longer  payment  cycles and  rigorous  informational  requirements  of some
insurance  companies  or  other  third  party  payors.  Proper   authorizations,
referrals  and  confirmation  of  coverage  for  patients,  as well as issues of
medical  necessity,  need to be addressed  prior to the  rendering of service to
assure prompt payment of claims. HMCA believes it is properly addressing billing
and collection  requirements  and issues for its clients and that its collection
rates are good.  Nevertheless,  the regulations and  requirements  applicable to
medical billing and collections could change in the future and result in reduced
or  delayed  collections.  Approximately  97%  of  the  receivables  billed  and
collected  by HMCA are  from  professional  corporations  owned  by  Raymond  V.
Damadian.

6.  Capitated  insurance  programs  could  adversely  affect  HMCA's  clients by
shifting a part of the financial  responsibility for patient care to the medical
providers.

     Certain HMO's and insurers have instituted  managed care programs where the
physician or physician  group is paid on a capitated  basis.  Under these plans,
the  physician is not paid  according to the  services  provided,  but is paid a
fixed  monthly fee per patient,  which in HMCA's  experience is based on age and
gender.  Currently,  approximately  12.3% of HMCA's  clients'  revenues are from
capitated  programs.  Under  capitated  insurance  programs,  the  physician  or
physician  practice  in  effect  bears  some of the risk in the  event a patient
requires  extensive  treatment.  In the event that HMCA's  client  primary  care
practices  experience a shortfall between the capitated payments and the cost of
providing  services,  the ability of those  practices to pay for HMCA's services
may be impaired.

7. The  profitability of HMCA could be adversely  affected if medical  insurance
reimbursement rate change.

     HMCA receives  substantially  all of its revenue from medical practices and
providers of MRI services.  Consequently,  HMCA would be indirectly  affected by
changes in medical  insurance  reimbursement  policies,  HMO policies,  referral
patterns,  no-fault  and  workers  compensation  reimbursement  levels and other
factors affecting the  profitability of a medical practice or MRI facility.  The
types of medical  providers  served by HMCA are (a) MRI  facilities  (b) primary
care practices and (c) physical therapy and rehabilitation practices.  There are
approximately 20 MRI facilities served by HMCA located in New York,  Florida and
Georgia.  The primary care  practices  served by HMCA consist of four offices in
New York and the physical therapy and rehabilitation  practices consist of eight
offices  located  primarily  in New York.  Approximately  40% of HMCA's  clients
revenues are generated from the no-fault and personal injury protection  claims.
Although we do not know of any pending adverse development affecting these types
of facilities, future changes in the reimbursement levels for MRI, primary care,
workers  compensation  or no fault  reimbursement,  or  changes  in  utilization
policies for MRI or physical  rehabilitation  therapy could adversely affect the
ability of HMCA's  clients to pay HMCA's fees. In addition,  HMCA depends on the
ability of the medical  practices and providers to attract and retain physicians
and other professional staff.

8. The  amortization  of the  goodwill on our balance  sheet will reduce  future
profits.

     HMCA acquired  businesses  which were  essentially  service  businesses for
purchase prices based on earnings  multiples rather than net tangible assets. As
the historical cost of the assets was small relative to the purchase price,  the
consolidated  balance sheet of Fonar, HMCA and Fonar's  subsidiaries  reflects a
net carrying  value of  approximately  $20.7 million in goodwill as at March 31,
2001. Before amortization,  the aggregate amount of goodwill attributable to the
acquisitions  was  approximately  $23.4 million.  Amortization of this goodwill,
which is over a period  of  twenty  (20)  years,  will  reduce  net  profits  by
approximately $1.2 million annually. This is a non-cash annual expense.

9.  Professional  liability  claims  against  HMCA  or its  clients  may  exceed
insurance coverage levels.

     Although with one exception,  HMCA does not provide medical services, it is
possible  that a patient  suing one of HMCA's  client  medical  practices or MRI
facilities  would also sue HMCA.  In Florida,  where the  corporate  practice of
medicine  is legally  permissible,  a  subsidiary  of HMCA in one case  provides
medical  care  through  employee  doctors  and could be subject to  professional
liability claims in the event of malpractice. Neither HMCA nor its clients carry
professional  liability  insurance but physicians  working for HMCA's clients or
for  HMCA's  subsidiaries  are  required  to  maintain  professional   liability
insurance in the minimum amount of  $1,000,000/$3,000,000.  Such insurance would
not cover HMCA or a client  professional  corporation,  however,  in the event a
claim were made which was not covered by the  physician's  insurance.  Claims in
excess of  insurance  coverage  might also have to be  satisfied  by HMCA or its
clients if they were named as defendants.

10. We do not carry product liability insurance and would have to pay any claims
from our revenues and capital resources.

     Fonar  does not carry  product  liability  insurance  but is  self-insured.
Consequently,  Fonar would have to pay from its own resources any valid products
liability claim. To date, Fonar has not had to pay any such claims.

11. We are dependant upon the services of Dr. Damadian.

     Our success is greatly  dependent upon the continued  participation  of Dr.
Raymond V. Damadian,  Fonar's founder,  Chairman of the Board and President. Dr.
Damadian  has acted as our CEO  since  1978 and will  continue  to do so for the
foreseeable  future. In addition to providing general supervision and direction,
he provides active direction, supervision and management of our sales, marketing
and research and development efforts. Loss of the services of Dr. Damadian would
have a material adverse effect on our business.  We do not have an employment or
noncompetition  agreement with Dr. Damadian. We do not currently carry "key man"
life insurance on Dr. Damadian.

12. Dr. Raymond V. Damadian has voting control of Fonar;  the management  cannot
be changed or the company sold without his agreement.

     Dr. Raymond V. Damadian, the President, Chairman of the Board and principal
stockholder  of Fonar is and will  continue  to be in  control of Fonar and in a
position to elect all of the  directors of Fonar.  As of March 31,  2001,  there
were outstanding  58,787,817 shares of common stock,  having one vote per share,
4,211 shares of Class B common  stock,  having ten votes per share and 9,562,824
shares of Class C common stock,  having 25 votes per share.  Of these totals Dr.
Damadian owned 2,488,274  shares of common stock and 9,561,174 shares of Class C
common stock,  giving him over 80% of the voting power of Fonar's  voting stock.
This  means that the  holders  of the  common  stock will not be able to control
decisions  concerning any merger or sale of Fonar,  the election of directors or
the determination of business and management policy.

13. The dilution  which may result from the payment of the  debentures in common
stock could be significant.

     The debentures can be converted at a price of $2.047 per share, which would
result in 2,198,339 shares of common stock being issued. If, however, the market
price for our common stock is less than $2.047 per share,  then the holders will
not convert and we will be left with the alternative of paying the debentures in
shares of common stock  valued,  for the purpose of payment,  at a discount from
the then current market value for the common stock.  This discounted value would
be the lesser of (1) 90% of the  average of the four  lowest  closing bid prices
during  the  preceding  calendar  month or (2) the  average  of the four  lowest
closing bid prices  during the  preceding  calendar  month less  $0.125.  If for
example,  we were paying the  debentures  in June,  2001,  then the  approximate
number of shares we would have to issue based on the formula  would be 3,435,115
or approximately 56% more shares then would be issued on conversion.  Since this
alternative  is  based  on  market  price,  there  is no  limit  on how  low the
determined  value could be.  Fonar does retain the option,  however,  to pay the
debentures in cash if they are not converted.

14. The  provisions of the  debentures  would subject  Fonar's  stockholders  to
further  dilution if we were to issue  common  stock at prices  below  market or
below the conversion price in the debentures.

     In addition to provisions  providing for  proportionate  adjustments in the
event of stock splits, stock dividends, reverse stock splits and similar events,
the debentures provide for an adjustment of the conversion price if Fonar issues
shares of common  stock at prices  lower than the  conversion  price or the then
prevailing market price. This means that if we need to raise equity financing at
a time  when the  market  price  for  Fonar's  common  stock  is lower  than the
conversion price, or if we need to provide a new equity investor with a discount
from the then prevailing market price, then the conversion price will be reduced
and the dilution to stockholders increased.

15. The provisions of the warrants  provide for reductions in the exercise price
if we issue common  stock at prices  below market or below the warrant  exercise
prices.

     In addition to provisions  providing for  proportionate  adjustments in the
event of stock splits, stock dividends, reverse stock splits and similar events,
the  warrants  provide for a reduction  of the  exercise  price if Fonar  issues
shares of common stock at prices lower than the exercise price or lower than the
then prevailing  market price.  Although the number of shares issuable under the
warrants  will not change in this case, we would receive less in proceeds if the
warrants were subsequently exercised.

                           FORWARD-LOOKING STATEMENTS

     We make  statements in this  prospectus and the documents  incorporated  by
reference that are considered  forward-looking  statements within the meaning of
the Securities Act of 1933 and the Securities  Exchange Act of 1934. The Private
Securities  Litigation  Reform Act of 1995  contains the safe harbor  provisions
that cover these forward-looking statements. We are including this statement for
purposes  of  complying  with  these  safe  harbor  provisions.  We  base  these
forward-looking  statements on our current  expectations  and projections  about
future  events.  These  forward-looking  statements are not guarantees of future
performance and are subject to risks,  uncertainties and assumptions  including,
among other things:

     -    continued losses and cash flow deficits;

     -    the continued  availability of financing in the amounts,  at the times
          and on the terms required to support our future business;

     -    uncertain market acceptance of our products; and

     -    reliance on key personnel.

     Words  such  as  "expect,"   "anticipate,"   "intend,"  "plan,"  "believe,"
"estimate" and variations of such words and similar  expressions are intended to
identify such forward-looking statements. We undertake no obligation to publicly
update or revise  any  forward-looking  statements,  whether  as a result of new
information,  future events or otherwise.  Because of these risks, uncertainties
and  assumptions,  the  forward-looking  events  discussed  or  incorporated  by
reference in this document may not occur.

                                 USE OF PROCEEDS

     We cannot  guarantee  the amount of the  proceeds  we will  receive in this
offering.  Whether the  debentures  will be converted or the warrants  exercised
will depend on the market price for Fonar's common stock.  We have received $4.5
million from the issuance of the debentures.  We will not receive any additional
proceeds from any conversions. Whether we receive any proceeds from the warrants
will depend on the market  price of our common  stock  relative to the  exercise
price under the warrants.

     We intend to use the net  proceeds of this  offering,  if any,  for general
corporate purposes, including working capital to fund operating losses, expenses
and capital expenditures.  As of the date of this prospectus,  we cannot specify
with certainty the  particular  uses for the net proceeds to be received in this
offering.  Accordingly,  our  management  will  have  broad  discretion  in  the
application of any net proceeds received. Pending such uses, we intend to invest
the net proceeds,  if any, from this offering in  short-term,  interest-bearing,
investment grade securities.

                              PLAN OF DISTRIBUTION

     All of the shares of common stock being offered by this  prospectus will be
issued upon the conversion or payment of our 4% convertible  debentures due June
30, 2002 or upon the exercise of our outstanding  purchase warrants and callable
warrants.

     The  debentures  are  convertible at the option of the holder at a price of
$2.047 per share. If the holders decide not to convert, then we would still have
the right to pay the  debentures  in shares of our common  stock,  but the stock
would be  valued  at the  lesser  of a) 90% of the  average  of the four  lowest
closing  bid prices  during the  preceding  month or b) the  average of the four
lowest closing bid prices during the preceding calendar month less $0.125.

     This means that if the holders of the debenture elect not to covert because
the market price for our common  stock is less than the  conversion  price,  the
selection  of the second  alternative  by Fonar will  result in a  significantly
lower  valuation  of our shares and greater  dilution to our  stockholders  than
would be the case in a conversion.

     We received the $4.5 million upon the issuance of the  debentures.  Whether
the debentures are converted or we elect to pay the debentures in stock, we will
not receive additional proceeds.

     The  purchase  warrants  cover  959,501  shares of common stock and have an
exercise price of $1.801 per share. The exercise period extends to May 24, 2006.
If all of the purchase warrants are exercised,  we would receive proceeds in the
approximate amount of $1.7 million.

     The callable  warrants  cover  2,000,000  shares of common stock and have a
variable  exercise  price.  Subject to a maximum  price of $6.00 per share and a
minimum  price of $2.00  per  share,  the  exercise  price  will be equal to the
average  closing bid price of Fonar's  common stock for the full calendar  month
preceding  the date of exercise.  The exercise  period  extends to May 24, 2004.
Since the exercise price varies, the amount of proceeds,  if any, which we would
receive cannot be predicted. At the minimum exercise price of $2.00 per share we
would receive proceeds of $4 million.

         No proceeds  can be expected  to be received  from the  exercise of the
warrants  unless  the  market  price  of our  common  stock is  higher  than the
applicable exercise prices.

     No  commissions  are payable by us or the holders of the debentures and the
warrants in connection with a conversion or exercise.

     We have the option of redeeming up to 200,000  callable  warrants per month
at a price of $0.01 per  underlying  warrant share,  if the average  closing bid
price of Fonar's  common  stock is  greater  than 115% of the  warrant  price in
effect for five consecutive trading days in any calendar month. We also have the
option of reducing the exercise  price under the callable  warrants to any lower
exercise price that was previously in effect.

     The debentures and warrants  provide for  proportionate  adjustments in the
event of stock splits,  stock  dividends and reverse stock splits.  In addition,
the  conversion  and exercise  prices will be reduced,  with  certain  specified
exceptions,  if we issue shares at lower prices then the debenture conversion or
warrant exercise prices, or less than market price for our common stock.

     The number of shares being registered,  by the terms of the agreements with
the Tail  Wind Fund is two times  the  number  of  shares  necessary  to pay the
debentures at the lower of the market price, as computed under the agreements or
conversion price, plus the number of shares underlying the warrants.

     In connection with the issuance of the debentures to The Tail Wind Fund, we
paid a  placement  fee to Roan  Meyers,  Inc.  in the  amount  of  $157,500.  In
addition, we issued 300,000 purchase warrants to Roan Meyers, Inc.

     Computershare  Trust Company,  Inc.,  formerly called  American  Securities
Transfer & Trust, Inc., located at 12039 W. Alameda Parkway, Lakewood,  Colorado
80228, is the transfer agent and registrar for our common stock.

                              SELLING STOCKHOLDERS

     Assuming that all 9,900,000 shares of common stock are issued to the owners
of the debentures and warrants upon conversion and exercise, the following chart
shows the owners and  certain  other  information.  The chart  assumes  that the
owners will resell all the shares they receive.

                                     Experts

     The consolidated  financial statements and supplemental financial schedules
contained  in  Fonar's  latest  annual  report  on Form  10-K,  incorporated  by
reference into this  prospectus,  has been examined by Tabb Conigliaro & McGann,
to the extent set forth in their report. Such financial statements and schedules
were included  therein in reliance upon their reports,  given on their authority
as  experts  in  accounting  and  auditing.  Subsequent  to their  report,  Tabb
Conigliaro & McGann merged into Grassi & Co., CPA's, P.C.

                                 INDEMNIFICATION

     The Delaware  General  Corporation  Law and Fonar's by-laws provide for the
indemnification  of an officer or director under certain  circumstances  against
reasonable  expenses  incurred  in  connection  with the  defense  of any action
brought  against him by reason of his being a director  or  officer.  Insofar as
indemnification  for  liabilities  arising  under  the  Securities  Act  may  be
permitted to directors,  officers or other persons under Fonar's  by-laws or the
Delaware General Corporation Law, Fonar has been informed that in the opinion of
the Securities and Exchange  Commission such  indemnification  is against public
policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section  102(b)(7) of the General  Corporation Law of the State of Delaware
(the  "Delaware  Law") grants  corporations  the right to limit or eliminate the
personal  liability of their  directors in certain  circumstances  in accordance
with provisions  therein set forth. Our Certificate of Incorporation  contains a
provision eliminating director liability to us and our stockholders for monetary
damages for breach of  fiduciary  duty as a director.  The  provision  does not,
however,  eliminate or limit the personal  liability of a director:  (i) for any
breach of such  director's duty of loyalty to us or our  stockholders;  (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing  violation of law; (iii) under the Delaware  statutory  provision making
directors personally liable, for improper payment of dividends or improper stock
purchases or redemptions;  or (iv) for any  transaction  from which the director
derived an improper personal benefit. This provision offers persons who serve on
our Board of Directors  protection  against awards of monetary damages resulting
from breaches of their duty of care (except as indicated  above). As a result of
this provision, our ability or a stockholder's ability to successfully prosecute
an  action  against  a  director  for a breach  of his duty of care is  limited.
However,  the provision does not affect the  availability of equitable  remedies
such as an injunction or rescission  based upon a director's  breach of his duty
of care.  The SEC has taken the position that the provision  will have no effect
on claims arising under federal securities laws.

     Section 145 of the Delaware Law grants  corporations the right to indemnify
their  directors,   officers,  employees  and  agents  in  accordance  with  the
provisions  therein set forth.  Our By-laws provide that the corporation  shall,
subject to limited exceptions, indemnify its directors and executive officers to
the fullest  extent not  prohibited  by the Delaware  Law.  Our By-laws  provide
further  that the  corporation  shall  have the  power to  indemnify  its  other
officers,  employees  and her  agents as set  forth in the  Delaware  Law.  Such
indemnification  rights  permit  reimbursement  for  expenses  incurred  by such
director,  executive officer, other officer, employee or agent in advance of the
final   disposition  of  such  proceeding  in  accordance  with  the  applicable
provisions of the Delaware Law.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and  controlling  persons of us
pursuant to these  provisions,  or otherwise,  we have been advised that, in the
opinion of the  Securities  and Exchange  Commission,  such  indemnification  is
against  public  policy  as  expressed  in the  Securities  Act of 1933  and is,
therefore, unenforceable.

Item 17. Undertakings

     The undersigned registrant hereby undertakes:

(a)  To file,  during  any  period in which  offers or sales are being  made,  a
     post-effective amendment to this registration statement: (i) To include any
     prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii)
     To  reflect  in the  prospectus  any  facts or  events  arising  after  the
     effective  date  of  the   registration   statement  (or  the  most  recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent  a  fundamental  change  in  the  information  set  forth  in the
     registration  statement.  Notwithstanding  the  foregoing,  any increase or
     decrease  in volume of  securities  offered (if the total  dollar  value of
     securities  offered  would not exceed  that which was  registered)  and any
     deviation from the low or high end of the estimated  maximum offering range
     may be  reflected  in the form of  prospectus  filed  with  the  Commission
     pursuant  to Rule  424(b) if, in the  aggregate,  the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set  forth in the  "Calculation  of  Registration  Fee"  table in the
     effective registration statement. (iii) To include any material information
     with respect to the plan of  distribution  not previously  disclosed in the
     registration  statement or any material  change to such  information in the
     registration statement.

(b)  That for the purpose of determining  any liability under the Securities Act
     of 1933,  each such  post-effective  amendment  shall be deemed to be a new
     registration  statement relating to the securities offered therein, and the
     offering of such  securities at that time shall be deemed to be the initial
     bona fide offering thereof.

(c)  To remove from  registration by means of a post-effective  amendment any of
     the securities  being  registered which remain unsold at the termination of
     the offering.

     The  undersigned  registrant  hereby  undertakes  that, for the purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual report  pursuant to section 13 (a) or section 15 (d) of the
Securities  Exchange  Act of  1934  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.



                                   SIGNATURES

     Pursuant to the  requirements of the Securities Act of 1933, the registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-3 and has  duly  caused  this  registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, on June 25, 2001.

Dated:  June 25, 2001
