A brief overview of the radiological imaging problem is presented, emphasizing the need for parametrizing components for the user, medical physicist, or system designer. Against this background a method is proposed for reducing MTF data. The single parameter obtained is analogous to criteria of “sharpness” used in other optical applications. The example of x-ray tube focal spots is examined in detail; results are presented and compared with other criteria. Finally, a prescription for cascading elements into a system is given and applied to the case of magnification radiography.
