     SUMMARY INFORMATION AND RISK FACTORS.

     On June 12, 1989 Interspec, Inc. ("Interspec") issued
certain convertible subordinated notes (the "Notes") by private 
placement to five Noteholders for the total principal amount 
of $10 million.  Under the terms of the Notes, the unpaid principal 
amount could be converted at the option of the Noteholders or
Interspec, under certain defined conditions, into common stock
of Interspec at a defined conversion price.  Repayments of
principal were made by Interspec through May, 1994, at which
time the unpaid principal amount was $6.5 million.

     On May 17, 1994 ATL acquired Interspec through a stock
for stock acquisition which was approved by the shareholders
of both companies.  The Company registered 2,588,000 shares of
Common Stock in April, 1994 to effect the merger. An election
to convert by either party at the time of the merger would
have resulted in the issuance of 383,480 shares of Common Stock 
to the Noteholders based upon the then outstanding principal 
amount of the Notes, $6.5 million, and the conversion ratio 
applicable to all Interspec shareholders.

     On November 30, 1995 the conditions under which the
Company had the right to convert the remaining principal
amounts of the Notes into Common Stock were satisfied, and the
Company gave the four remaining Noteholders notice of its
intent to effect such a conversion on February 1, 1996.  The
repayments of principal since the time of the merger had, by
November 30, 1995, reduced the principal amount of the Notes
to $3,375,000, and have thereby reduced the number of shares
required for the conversion.  The Shares registered hereby 
comprises Common Stock which which has been received by the 
Noteholders in lieu of cash payments of principal under the Notes.  
Details on all holdings of Common Stock by the Noteholders 
which are known to the Company are given in the table below.  
See "The Notes and the Noteholders."

     A prospective purchaser of the Shares should take into
account the following:

     Lack of Diversification.  The Company is engaged
primarily in the diagnostic medical ultrasound business.
Consequently, the Company is subject to adverse developments
in the healthcare industry generally, and in particular in the
medical ultrasound business as a result of competition,
technological change, governmental regulation, change in third
party reimbursement policies, third party intellectual
property claims, seasonal fluctuations in medical equipment
purchasing, or other factors to a greater extent than a
company with a more diverse business.

     Volatility of Stock Price; Absence of Dividends. The
market price for securities of medical technology companies
has historically been volatile.  Among other things, announcements 
of technical innovations or new commercial products by ATL or its 
competitors, development concerning proprietary rights, including patents
and litigation matters, publicity regarding actual or potential 
medical results with products under development by ATL or its 
competitors, and regulatory developments in both the United States 
and foreign countries, as well as period-to-period fluctuations 
in revenues and financial results, can have a significant impact on the 
market price of ATL Common Stock.  The Company does not pay cash 
dividends on shares of Common Stock.

     Intense Competition.  The markets for diagnostic medical
ultrasound products are intensely competitive.  ATL faces
competition from many domestic and foreign companies.  Several
of the Company's competitors have far greater financial,
marketing, servicing, technical and research and development
resources than those of ATL.  Several of these competitors
have recently intensified their efforts in the market for

Page 3



diagnostic ultrasound and have introduced new lines of
products which compete with those of ATL.  Several of these
competitors have the ability to combine their resources in
ultrasound with those of other medical imaging modalities,
including the servicing of these product lines.  There can be
no assurance that actual or potential competitors will not
develop and market products which compete effectively with
those of ATL.  Competition could adversely affect the
Company's revenues and profitability.

     Recent Losses.  For the fiscal year ending December 31, 1994 
the Company reported a loss of $20.2 million, including non-recurring 
charges of $12.0 million comprising $7.0 million for the acquisition 
of Interspec and restructuring expenses associated with corporate 
streamlining activities and a provision of $5.0 million for a patent 
litigation claim.  For the first nine months of 1995 the Company reported
a net loss of $0.2 million, including restructuring and relocation
expenses of $4.7 million associated with the consolidation of the 
Company's Interspec operations in Ambler, Pennsylvania.  The Company 
has reported that it expects to incur relocation and restructuring 
expenses in 1995 of approximately $6.0 million associated with this
consolidation.  There can be no assurance that losses will not be 
sustained in the future or that profitability will be achieved by 
the Company on a short or long term basis.

     Rapid Technological Change.  The diagnostic medical ultrasound 
business is characterized by rapidly evolving technology and 
continuing competitive pressure to develop and market new products 
and product features.  The complexity of the Company's products could 
result in delays in product delivery as improvements and new features 
are made to the hardware and software of the products.  There can be no
assurance that product changes and modifications in the factory and in 
the field will not result in disruption of product sales and shipments, 
or additional expense, in any particular period.  There can be no 
assurance that the Company will be able to develop and market new 
competitive products on a cost-effective and timely basis, that such 
products will compete favorably with products developed by others, or 
that the Company's existing technology will not be superseded by new 
technology developed by competitors.

     Government Regulation.  ATL's manufacturing facilities,
products, and product labeling are subject to extensive and
rigorous governmental regulation by the U.S. Food and Drug
Administration (FDA) and corresponding state and foreign
agencies.  In conjunction with the processing of the Company's
PMA application (see "Recent Developments"), the FDA is
currently auditing the Company's products and processes for
compliance with FDA rules and regulations.  There can be no
assurance that the Company will be able to timely obtain
necessary regulatory approvals in the future, and delays in
the receipt of or failure to receive such approvals, the loss
of existing approvals, failure to comply with regulatory
requirements, and the cost of bringing products and processes
into compliance with regulatory requirements could have a
material adverse effect on the business, financial condition
and results of operations of the Company.

     Uncertain Healthcare Environment.  Uncertainty of
healthcare legislation and economic conditions in recent years
have caused healthcare providers who purchase capital medical
equipment including ultrasound equipment to exercise caution
in making capital purchases.  This has led to a deferral in
the purchase of ultrasound and other capital equipment.  These
conditions and others have led to the consolidation of many
healthcare providers and a consequent reduction in the medical
capital equipment markets in some countries.  The continuing
effects of such uncertainty both domestically and in
international markets may continue to adversely affect the
Company's unit volumes, product pricing, and profit margins.

     Dependence on Third-Party Reimbursement.  ATL's products
are used by healthcare providers for medical services for
which the provider may seek reimbursement of purchase and/or
use costs from various third-party payors such as government
programs and private health insurance plans.  Such reimbursement 
is subject to the regulations and policies of governmental agencies 
and third-party payors.  The Company cannot predict what changes 
may occur in these regulations and policies, nor the effect of 
such changes on the business of the Company.

     Uncertainty of Patents and Proprietary Rights.  Companies
in technology businesses routinely review the products of
others for possible conflict with their own patent rights.
ATL from time to time receives notices of claims from others
alleging patent infringement.  ATL is currently awaiting a
decision on damages payable by the Company in an infringement
action on an expired patent in which the plaintiff is seeking
over $5 million in 

Page 4


damages, and a threefold enhancement of damages.  There can be 
no assurance that the Company will not be subject to other claims 
of patent infringement or that a claim will not require that the 
Company pay substantial damages or delete certain features from 
its products or both. Such claims could temporarily interrupt the 
Company's ability to ship affected products.

     Dependence on Suppliers For Critical Components.  ATL
depends on some single-source vendors for certain important
component parts for certain products.  Such vendors can
occasionally experience problems with their ability to deliver
components needed by the Company, and certain components have
long lead-times for delivery.  An abrupt disruption in the
supply of these components could have a material adverse
effect on the Company's production of affected products.


     RECENT DEVELOPMENTS.

     On December 11, 1995 a U.S. Food and Drug Administration
(FDA) Advisory Committee Panel voted unanimously to recommend
FDA approval, with certain modifications, of the pre-market
approval (PMA) application of ATL which would allow a new
clinical application of ultrasound, in conjunction with
mammography, to provide a high level of confidence in
differentiating benign from malignant or suspicious breast
lesions, and thereby reduce the need for breast biopsy.  The
FDA usually follows the recommendation of its Advisory
Committee Panel but is not obliged to do so.  A final
determination on approval of the PMA is expected in early
1996.

     USE OF PROCEEDS.

     The Shares offered are being registered for the accounts
of the Noteholders and, accordingly, the Company will not
receive any proceeds from the sale of the Shares.


     THE NOTES AND THE NOTEHOLDERS.

     The Notes were issued to the Noteholders on June 12, 1989
by Interspec, Inc., and interest of 11% per annum on the
outstanding principal amount of the Notes has been paid
semiannually since their issue date.  The initial principal
amount of the Notes was $10 million.  Of this initial amount,
$3.5 million was repaid prior to the merger of Interspec and
the Company in May, 1994, and $2,632,353 has been repaid in
accordance with the terms of the Notes since May, 1994.  The
principal amount of the Notes which has been repaid in the
form of the Shares which are the subject of this registration 
statement is $3,617,605.

     On May 17, 1994 the Company acquired Interspec in a stock
for stock acquisition approved by the shareholders of both
companies.  As a consequence thereof, the Company guaranteed
the repayment of the Notes and the Notes were amended to
become convertible into Common Stock at the option of the
Company at a conversion price of $16.95 per share (subject to
certain adjustments which have not occurred) in the event the
market price of the Common Stock exceeded the conversion price
by at least 20% for fifteen consecutive trading days.  These
criteria were satisfied on November 30, 1995 and notice of the
Company's election to convert the Notes was given to all
Noteholders on November 30, 1995. The Company intends to
complete the conversion by the issuance to the Noteholders of
all Shares by February 1, 1996.

     The Shares are being registered pursuant to the terms of
a Registration Agreement of July 14, 1988 between Interspec
and various Interspec securityholders, as amended June 12,
1989, which provides the Noteholders with certain "demand"
registration rights.  The demand registration rights of the
Noteholders terminate on May 17, 1999.  Pursuant thereto, the
Company has agreed to keep any registration statement and 
prospectus filed in connection therewith effective for a
period of not less than six months.  The Registration
Agreement includes a right of the Noteholders to be
indemnified against losses due to a material omission or
untrue statement in a registration statement or prospectus
filed pursuant thereto.

     The following table sets forth certain information
regarding the beneficial ownership of shares of Common Stock
by the Noteholders as of December 31, 1995, as adjusted to
reflect the acquisition and sale of the Shares to be
registered hereby.  Other than their status as Noteholders, no
Noteholder held any position or office or other material
relationship with the Company or with Interspec during the
past three years.  As of December 31, 1995 there were
13,609,731 shares of the Company's Common Stock outstanding.

(1) Includes all Shares issuable upon conversion of the Notes
held by the Selling Shareholders.

(2) Assumes a disposition of all Shares, and retention of all
previously owned Common Stock, at the conclusion of the
offering.

(3) Includes 14,315 Shares to be issued to State Farm in
lieu of a remaining cash principal repayment on December 29, 1994 
and 71,577 Shares issued to State Farm in lieu of a cash principal 
repayment on February 1, 1996.

                               
                               
     PLAN OF DISTRIBUTION.

     The sale of Shares by the Selling Shareholders may be
effected from time to time in one or more transactions (which
may involve block transactions), in special offerings,
secondary distributions, in negotiated transactions, or a
combination or such methods of sale, at market prices
prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.  Such
transactions may be effected on the over-the-counter market.
The Selling Shareholders may effect such transactions by
selling the Shares to or through broker-dealers, and such
broker-dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from one or
more of the Selling Shareholders for whom they may act as
agent (which compensation may be in excess or customary
commissions).  Without limiting the foregoing, such brokers
may act as dealers by purchasing any and all of the Shares
covered by this Prospectus either as agents for others or as
principals for their own accounts and reselling such
securities pursuant to this Prospectus.  The Selling
Shareholders and any broker-dealers or other persons acting on
their behalf that participate with such Selling Shareholders
in the distribution of the Shares may be deemed to be
underwriters, and any commissions received or profit realized
by them on the resale of the Shares may be deemed to be
underwriting discounts and commissions under the Securities
Act.  As of the date of this Prospectus the Company is not
aware of any agreement arrangement or understanding between
any broker or dealer and any of the Selling Shareholders.

     At the time that any particular offering of Shares is
made, to the extent required by the Securities Act, an
amendment or a prospectus supplement will be distributed,
setting forth the terms of the offering, including the
aggregate number of Shares being offered, the names of any
underwriters, dealers or agents, and discounts, commissions
and other items constituting compensation from the Selling
Shareholders and any discounts, commissions or concessions
allowed or reallowed or paid to dealers.

Page 6



     The Selling Shareholders may from time to time pledge the
Shares owned by them to secure margin or other loans made to
one or more of the Selling Shareholders.  Thus the person or
entity receiving the pledge of any of the Shares may sell
them, in a foreclosure sale or otherwise, in the same manner
as described above for a Selling Shareholder.

     The Company intends the term of effectiveness of this
registration statement to continue for six months from the
date the registration statement becomes effective.

                               
     LEGAL MATTERS

     The validity of the issuance of Shares of Common Stock
offered hereby will be passed upon for the Company by Bogle &
Gates P.L.L.C., Seattle, Washington.

ITEM 15.  Indemnification Of Directors And Officers


    The Company's Articles of Incorporation provide that the
Company may indemnify and hold harmless to the fullest extent
permitted by the Washington Business Corporation Act (the
"WBCA") or other applicable law each person who was or is made
a party to or is threatened to be made a party to or is
involved (including, without limitation, as a witness) in any
actual or threatened action, suit or other proceeding, whether
civil, criminal, derivative, administrative or investigative,
by reason of the fact that he or she is or was a director,
officer, employee or agent of the Company or, being or having
been such a director, officer, employee or agent, he or she is
or was serving at the request of the Company as a director,
officer, employee, agent, trustee, or in any other capacity of
another Company or of a partnership, joint venture, trust or
other enterprise, including service with respect to employee
benefit plans, whether the basis of such proceeding is alleged
action or omission in an official capacity or in any other
capacity while serving as a director, officer, employee,
agent, trustee or in any other capacity, against all expense,
liability and loss (including, without limitation, attorneys'
fees, judgments, fines, Employee Retirement Income Security
Act of 1974 excise taxes or penalties and amounts to be paid
in settlement) actually or reasonably incurred or suffered by
such person in connection therewith.  The WBCA includes a
provision (Section 23B.08.320 of the Revised Code of
Washington) that permits a corporation to limit a director's
liability to the corporation or its shareholders for monetary
damages for his or her acts or omissions as a director, except
in certain circumstances involving intentional misconduct,
self dealing, knowing violation of the law, or illegal
corporate loans or distributions, or any transaction from which 
the director personally benefits.  Such indemnification may 
continue as to a person who has ceased to be a director, officer, 
employee or agent of the Company and shall inure to the benefit 
of his or her heirs and personal representatives.

    The Company may pay the expenses of a director, officer,
employee or agent of the Company incurred in defending any
such proceeding in advance of the final disposition of any
such proceeding; provided, however, that the payment of such
expenses in advance of the final disposition of a proceeding
shall be made to or on behalf of a director, officer, employee
or agent only upon delivery to the Company of an undertaking,
by or on behalf of such director, officer, employee or agent,
to repay all amounts so advanced if it shall ultimately be
determined that such director, officer, employee or agent is
not entitled to be indemnified under the Company's Articles of
Incorporation or otherwise, which undertaking may be unsecured
and may be accepted without reference to financial ability to
make repayment.

Page II-1



    No indemnification shall be provided under the Company's
Articles of Incorporation to any such person if the Company is
prohibited by the provisions of the WBCA or other applicable
law as then in effect from paying such indemnification.  The
WBCA (Sections 23B.08.500 through 23B.08.600 of the Revised
Code of Washington) authorizes a court to award, or a
corporation's board of directors to grant, indemnity to
directors and officers in terms sufficiently broad to permit
such indemnification under certain circumstances for
liabilities arising under the WBCA.

     The Company also maintains an insurance policy insuring
its directors and officers against liability for certain acts
or omissions while acting in their official capacities.

ITEM 17.  Undertakings

A.   Rule 415 Offering.
     ------------------

     The undersigned registrant hereby undertakes:

(1)  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, as amended (the "Securities Act");

     (ii) To reflect in the prospectus any facts or events arising 
after the effective date of this 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 this 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 for the low or high
and 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 percent 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 this 
registration statement or any material change to such information 
in this registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) above do
not apply if the information required to be included in a post-
effective amendment by those paragraphs is contained in
periodic reports filed by the Company pursuant to Section 13
or Section 15(d) of the Exchange Act that are incorporated by
reference in this registration statement.

(2)  That, for the purpose of determining any liability under
the Securities Act, 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.

(3)  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.

B.   Filings Incorporating Subsequent Exchange Act Documents by Reference.
     --------------------------------------------------------------------

     The undersigned registrant hereby undertakes that, for purposes 
of determining any liability under the Securities Act, each filing of 
the registrant's annual report pursuant to Section 13(a) or 15(d) of 
the Exchange Act (and, where applicable, each filing of an employee 
benefits plan's annual report pursuant to Section 15(d) of the Exchange 
Act) that is incorporated by reference in this registration statement 
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.

Page II-3



H.   Indemnification for Liabilities.
     --------------------------------

     Insofar as indemnification for liabilities arising under
the Securities Act 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 Securities 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 
Securities Act and will be governed by the final adjudication of such issue.
                               
Page II-4



                               SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, as 
amended, 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
