Re:  OrthoLogic Corp.
     Registration Statement on Form S-3, as amended
     File No. 333-133273

Ladies and Gentlemen:

     Pursuant to Rule 477 of Regulation C under the Securities Act of 1933, as
amended (the "Securities Act"), OrthoLogic Corp. (the "Registrant") hereby
requests that its Registration Statement on Form S-3 (File No. 333-133273)
initially filed on April 13, 2006, as amended in an Amendment No. 1 filed on
September 22, 2006, together with all exhibits thereto (the "Registration
Statement"), be withdrawn. The Registrant is submitting this application for
withdrawal because the transactions that contemplated the offer and sale of the
securities covered by the Registration Statement have changed and, thus, the
Registration Statement is no longer necessary. The Registrant confirms that no
securities of the Registrant have been sold pursuant to the Registration
Statement.

     The Registrant respectfully requests that, in accordance with Rule 457(p)
under the Securities Act, all fees paid to the Securities and Exchange
Commission in connection with the filing of the Registration Statement be
credited to the Registrant's account for future use.

     If you have any questions with respect to this matter, please contact the
Registrant's counsel, Steven P. Emerick, Esq. of Quarles & Brady Streich Lang
LLP, at (602) 230-5517.

                                   Sincerely,

                                   OrthoLogic Corp.


                                   /s/ Les M. Taeger
