Gentlemen:

     We are providing this opinion in connection with the Registration Statement
of OrthoLogic Corp. (the "COMPANY") on Form S-8 (the "REGISTRATION STATEMENT")
filed under the Securities Act of 1933, as amended (the "ACT"), with respect to
the proposed sale of up to 2,150,000 additional shares of Common Stock, $0.0005
par value, of the Company (the "SHARES") pursuant to the OrthoLogic Corp. 1997
Stock Option Plan (the "PLAN"). We have examined (i) the Registration Statement;
(ii) the Company's Amended and Restated Certificate of Incorporation and Bylaws,
as amended to date; (iii) the Plan; (iv) corporate proceedings relating to the
adoption of the Plan and the issuance of the Shares; and (v) such other
documents and records as we have deemed necessary in order to render this
opinion. In rendering this opinion, we have relied as to certain factual matters
on certificates of officers of the Company and of state officials.

     Based upon the foregoing, it is our opinion that the Shares, when issued
and paid for as contemplated by the Registration Statement and the Plan, will be
validly issued, fully paid and non-assessable by the Company.

     We consent to the filing of this opinion as an Exhibit to the Registration
Statement. In giving our consent, we do not admit that we are "experts" within
the meaning of Section 11 of the Act, or that we come within the category of
persons whose consent is required by Section 7 of the Act.

                                        Very truly yours,

                                        /s/ QUARLES & BRADY STREICH LANG LLP

                                        QUARLES & BRADY STREICH LANG LLP
