Exhibit 4.2

                          REGISTRATION RIGHTS AGREEMENT


     THIS REGISTRATION RIGHTS AGREEMENT, made as of December 22, 2004, by and
between In Vivo Medical Diagnostics, Inc., a Colorado corporation (the
"Company"), and the person whose name appears on the signature page attached
hereto (the "Holder") issued in the private placement offering.

     WHEREAS, the parties are entering into a Subscription Agreement (the
"Subscription Agreement"), in connection with the proposed private placement
(the "Bridge Loan") of the Company's units ("Units") consisting of (i) a
$250,000, 8% promissory note (the "Note"); and (ii) 60,096 shares of the
Company's common stock (the "Common Stock or the "Bridge Shares");

     WHEREAS, pursuant to the terms of and in order to induce the Holder to
enter into a certain subscription agreement dated the date hereof between the
Company and the Holders (the "Subscription Agreement") to purchase the Units,
the Company and the Holder have agreed to enter into this Agreement; and

     WHEREAS, it is intended by the Company and the Holder that this Agreement
shall become effective immediately upon the acquisition by the Holder of the
Units;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the Company hereby agrees as follows:

     1. Piggyback Registration. If the Company at any time after the date hereof
but before the first anniversary of the date hereof proposes to register any of
its securities under the Securities Act of 1933, as amended (the "1933 Act")
(other than pursuant to a registration statement in connection with an
acquisition or in a manner which would not permit the registration of the Bridge
Shares for sale to the public, such as on Form S-8 or on Form S-4 or other
comparable form)("Company Registration"), the Company shall include the Bridge
Shares (referred to as the "Registerable Securities") in such registration.
Provided, however, that if, at any time after giving such written notice of the
Company's intention to register any of the Holder's Registerable Securities and
prior to the effective date of the registration statement filed in connection
with such registration, the Company shall determine for any reason not to
register or to delay the Company Registration, the Company may give written
notice of such determination to the Holder and thereupon shall be relieved of
its obligation to register any Registerable Securities issued or issuable in
connection with such registration (but not from its obligation to pay
registration expenses in connection therewith or to register the Registerable
Securities in a subsequent registration); and in the case of a determination to
delay a registration shall thereupon be permitted to delay registering any
Registerable Securities for the same period as the delay in respect of
securities being registered for the Company's own account.

     2. Cooperation with Company. The Holder will cooperate with the Company in
all respects in connection with this Agreement, including, timely supplying all
information reasonably requested by the Company and executing and returning all
documents reasonably requested in connection with the registration and sale of
the Registerable Securities.



     3. Registration Procedures. If and whenever the Company is required by any
of the provisions of this Agreement to use its best efforts to effect the
registration of any of the Registerable Securities under the 1933 Act, the
Company shall (except as otherwise provided in this Agreement), as expeditiously
as possible:

          a. prepare and file with the Securities and Exchange Commission (the
     "Commission") a registration statement and shall use its best efforts to
     cause such registration statement to become effective and remain effective
     until all the Registerable Securities are sold or become capable of being
     publicly sold without registration under the 1933 Act.

          b. prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the 1933 Act with
     respect to the sale or other disposition of all securities covered by such
     registration statement whenever the Holder of such securities shall desire
     to sell or otherwise dispose of the same (including prospectus supplements
     with respect to the sales of securities from time to time in connection
     with a registration statement pursuant to Rule 415 of the Commission);

          c. furnish to the Holder such numbers of copies of a summary
     prospectus or other prospectus, including a preliminary prospectus or any
     amendment or supplement to any prospectus, in conformity with the
     requirements of the 1933 Act, and such other documents, as such Holder may
     reasonably request in order to facilitate the public sale or other
     disposition of the securities owned by such Holder;

          d. use its best efforts to register and qualify the securities covered
     by such registration statement under such other securities or blue sky laws
     of such jurisdictions as each Holder shall reasonably request, and do any
     and all other acts and things which may be necessary or advisable to enable
     such Holder to consummate the public sale or other disposition in such
     jurisdiction of the securities owned by such Holder, except that the
     Company shall not for any such purpose be required to qualify to do
     business as a foreign corporation in any jurisdiction wherein it is not so
     qualified or to file therein any general consent to service of process;

          e. use its best efforts to list such securities on any securities
     exchange on which any securities of the Company is then listed, if the
     listing of such securities is then permitted under the rules of such
     exchange;

          f. enter into and perform its obligations under an underwriting
     agreement, if the offering is an underwritten offering, in usual and
     customary form, with the managing underwriter or underwriters of such
     underwritten offering;

                                        2


          g. notify the Holder of Registerable Securities covered by such
     registration statement, at any time when a prospectus relating thereto
     covered by such registration statement is required to be delivered under
     the 1933 Act, of the happening of any event of which it has knowledge as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing; and

          h. furnish, at the request of the Holder on the date such Registerable
     Securities are delivered to the underwriters for sale pursuant to such
     registration or, if such Registerable Securities are not being sold through
     underwriters, on the date the registration statement with respect to such
     Registerable Securities becomes effective, (i) an opinion, dated such date,
     of the counsel representing the Company for the purpose of such
     registration, addressed to the underwriters, if any, and to the Holder
     making such request, covering such legal matters with respect to the
     registration in respect of which such opinion is being given as the Holder
     of such Registerable Securities may reasonably request and are customarily
     included in such an opinion and (ii) letters, dated, respectively, (1) the
     effective date of the registration statement and (2) the date such
     Registerable Securities are delivered to the underwriters, if any, for sale
     pursuant to such registration from a firm of independent certified public
     accountants of recognized standing selected by the Company, addressed to
     the underwriters, if any, and to the Holder making such request, covering
     such financial, statistical and accounting matters with respect to the
     registration in respect of which such letters are being given as the Holder
     of such Registerable Securities may reasonably request and are customarily
     included in such letters.


     4. Expenses. All expenses incurred in any registration of the Holder's
Registerable Securities under this Agreement shall be paid by the Company,
including, without limitation, printing expenses, fees and disbursements of
counsel for the Company, expenses of any audits to which the Company shall agree
or which shall be necessary to comply with governmental requirements in
connection with any such registration, all registration and filing fees for the
Holder's Registerable Securities under federal and State securities laws, and
expenses of complying with the securities or blue sky laws of any jurisdictions;
provided, however, the Company shall not be liable for (a) any discounts or
commissions to any underwriter; (b) any stock transfer taxes incurred with
respect to Registerable Securities sold in the Offering or (c) the fees and
expenses of counsel for any Holder, provided that the Company will pay the costs
and expenses of Company counsel when the Company's counsel is representing any
or all selling security holders.

     5. Indemnification. In the event any Registerable Securities are included
in a registration statement pursuant to this Agreement:

                                        3


          a. Company Indemnity. Without limitation of any other indemnity
     provided to the Holder, either in connection with the Offering or
     otherwise, to the extent permitted by law, the Company shall indemnify and
     hold harmless the Holder, the affiliates, officers, directors and partners
     of each Holder, any underwriter (as defined in the 1933 Act) for such
     Holder, and each person, if any, who controls such Holder or underwriter
     (within the meaning of the 1933 Act or the Securities Exchange Act of 1934
     (the "Exchange Act"), against any losses, claims, damages or liabilities
     (joint or several) to which they may become subject under the 1933 Act, the
     Exchange Act or other federal or state law, insofar as such losses, claims,
     damages or liabilities (or actions in respect thereof) arise out of or are
     based upon any of the following statements, omissions or violations
     (collectively a "Violation"): (i) any alleged untrue statement of a
     material fact contained in such registration statement including any
     preliminary prospectus or final prospectus contained therein or any
     amendments or supplements thereto, (ii) the alleged omission to state
     therein a material fact required to be stated therein, or necessary to make
     the statements therein, (iii) any violation or alleged violation by the
     Company of the 1933 Act, the Exchange Act, or (iv) any state securities law
     or any rule or regulation promulgated under the 1933 Act, the Exchange Act
     or any state securities law, and the Company shall reimburse each such
     Holder, affiliate, officer or director or partner, underwriter or
     controlling person for any legal or other expenses incurred by them in
     connection with investigating or defending any such loss, claim, damage,
     liability or action; provided, however, that the Company shall not be
     liable to the Holder in any such case for any such loss, claim, damage,
     liability or action to the extent that it arises out of or is based upon a
     violation which occurs in reliance upon and in conformity with written
     information furnished expressly for use in connection with such
     registration by any such Holder or any other officer, director or
     controlling person thereof.

          b. Holder Indemnity. The Holder shall indemnify and hold harmless the
     Company, its affiliates, its counsel, officers, directors and
     representatives, any underwriter (as defined in the 1933 Act) and each
     person, if any, who controls the Company or the underwriter (within the
     meaning of the 1933 Act or liabilities (joint or several) to which they may
     become subject under the 1933 Act, the Exchange Act or any state securities
     law, and the Company shall reimburse each such Holder, affiliate, officer
     or director or partner, underwriter or controlling person for any legal or
     other expenses incurred by them in connection with investigating or
     defending any loss, claim, damage, liability or action; insofar as such
     losses, claims, damages or liabilities (or actions and respect thereof)
     arise out of or are based upon any statements or information provided by
     such Holder to the Company in connection with the offer or sale of
     Registerable Securities.

          c. Notice; Right to Defend. Promptly after receipt by an indemnified
     party under this Section 5 of notice of the commencement of any action
     (including any governmental action), such indemnified party shall, if a
     claim in respect thereof is to be made against any indemnifying party under
     this Section 5 deliver to the indemnifying party a written notice of the
     commencement thereof and the indemnifying party shall have the right to
     participate in and if the indemnifying party agrees in writing that it will
     be responsible for any costs, expenses, judgments, damages and losses
     incurred by the indemnified party with respect to such claim, jointly with
     any other indemnifying party similarly noticed, to assume the defense
     thereof with counsel mutually satisfactory to the parties; provided,
     however, that an indemnified party shall have the right to retain its own
     counsel, with the fees and expenses to be paid by the indemnifying party,

                                        4


     if the indemnified party reasonably believes that representation of such
     indemnified party by the counsel retained by the indemnifying party would
     be inappropriate due to actual or potential differing interests between
     such indemnified party and any other party represented by such counsel in
     such proceeding. The failure to deliver written notice to the indemnifying
     party within a reasonable time of the commencement of any such action shall
     relieve such indemnifying party of any liability to the indemnified party
     under this Agreement only if and to the extent that such failure is
     prejudicial to its ability to defend such action, and the omission so to
     deliver written notice to the indemnifying party will not relieve it of any
     liability that it may have to any indemnified party otherwise than under
     this Agreement.

          d. Contribution. If the indemnification provided for in this Agreement
     is held by a court of competent jurisdiction to be unavailable to an
     indemnified party with respect to any loss, liability, claim, damage or
     expense referred to therein, then the indemnifying party, in lieu of
     indemnifying such indemnified party thereunder, shall contribute to the
     amount paid or payable by such indemnified party as a result of such loss,
     liability, claim, damage or expense in such proportion as is appropriate to
     reflect the indemnified party on the other hand in connection with the
     statements or omissions which resulted in such loss, liability, claim,
     damage or expense as well as any other relevant equitable considerations.
     The relevant fault of the indemnifying party and the indemnified party
     shall be determined by reference to, among other things, whether the untrue
     or alleged untrue statement of a material fact or the omission to state a
     material fact relates to information supplied by the indemnifying party or
     by the indemnified party and the parties' relative intent, knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission. Notwithstanding the foregoing, the amount the Holder shall be
     obligated to contribute pursuant to the Agreement shall be limited to an
     amount equal to the proceeds to such Holder of the Registerable Securities
     sold pursuant to the registration statement which gives rise to such
     obligation to contribute (less the aggregate amount of any damages which
     the Holder has otherwise been required to pay in respect of such loss,
     claim, damage, liability or action or any substantially similar loss,
     claim, damage, liability or action arising from the sale of such
     Registerable Securities).

          e. Survival of Indemnity. The indemnification provided by this
     Agreement shall be a continuing right to indemnification and shall survive
     the registration and sale of any Registerable Securities by any person
     entitled to indemnification hereunder and the expiration or termination of
     this Agreement.

     6. Remedies.

          a. Time is of Essence. The Company agrees that time is of the essence
     of each of the covenants contained herein and that, in the event of a
     dispute hereunder, this Agreement is to be interpreted and construed in a
     manner that will enable the Holders to sell their Registerable Securities
     as quickly as possible after such Holders have indicated to the Company
     that they desire their Registerable Securities to be registered. Any delay
     on the part of the Company not expressly permitted under this Agreement,
     whether material or not, shall be deemed a material breach of this
     Agreement.

                                        5


          b. Remedies Upon Default or Delay. The Company acknowledges the breach
     of any part of this Agreement may cause irreparable harm to a Holder and
     that monetary damages alone may be inadequate. The Company therefore agrees
     that the Holder shall be entitled to injunctive relief or such other
     applicable remedy as a court of competent jurisdiction may provide. Nothing
     contained herein will be construed to limit a Holder's right to any
     remedies at law, including recovery of damages for breach of any part of
     this Agreement.

     7. Notices.

          a. All communications under this Agreement shall be in writing and
     shall be mailed by first class mail, postage prepaid, or telegraphed or
     telexed with confirmation of receipt or delivered by hand or by overnight
     delivery service,

          b. If to the Company, at:

     or at such other address as it may have furnished in writing to the
     Holders of Registerable Securities at the time outstanding, or

          c. if to the Holder of any Registerable Securities, to the address of
     such Holder as it appears in the stock ledger of the Company.

          d. Any notice so addressed, when mailed by registered or certified
     mail shall be deemed to be given three days after so mailed, when
     telegraphed or telexed shall be deemed to be given when transmitted, or
     when delivered by hand or overnight shall be deemed to be given when
     delivered.

     8. Successors and Assigns. Except as otherwise expressly provided herein,
this Agreement shall inure to the benefit of and be binding upon the successors
and permitted assigns of the Company and each of the Holders.

     9. Amendment and Waiver. This Agreement may be amended, and the observance
of any term of this Agreement may be waived, but only with the written consent
of the Company and the Holder. No delay on the part of any party in the exercise
of any right, power or remedy shall operate as a waiver thereof, nor shall any
single or partial exercise by any party of any right, power or remedy preclude
any other or further exercise thereof, or the exercise of any other right, power
or remedy.

                                        6


     10. Counterparts. One or more counterparts of this Agreement may be signed
by the parties, each of which shall be an original but all of which together
shall constitute one and same instrument.

     11. Governing Law. This Agreement shall be construed in accordance with and
governed by the internal laws of the State of New York, without giving effect to
conflicts of law principles.

     12. Invalidity of Provisions. If any provision of this Agreement is or
becomes invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein shall not be
affected there.

     13. Headings. The headings in this Agreement are for convenience of
reference only and shall not be deemed to alter or affect the meaning or
interpretation of any provisions hereof.

     IN WITNESS WHEREOF, the undersigned has executed this Agreement as of the
22nd day of December, 2004.
