Patent ID: 7775714

Claim:
A method of assessing performance quality of an imaging system having a sensor subsystem, providing at least one imaging mode of operation, and storing at least one previously acquired set of digital image data of an imaging phantom device representing a standard image of quality corresponding to said at least one imaging mode of operation, said method comprising: selecting and entering an imaging mode of operation of said imaging system; positioning an imaging phantom device with respect to said sensor subsystem; acquiring at least one current set of digital image data of said imaging phantom device with said imaging system via said sensor subsystem; automatically comparing said at least one currently acquired set of digital phantom image data to at least one previously acquired set of digital phantom image data representing a standard image of quality and corresponding to said selected imaging mode of operation and said imaging phantom device; automatically determining, in response to said comparing, at least one imaging parameter difference; and automatically correlating said at least one imaging parameter difference to a change in at least one sensor parameter of said sensor subsystem.
