ABSTRACT
Specifying and evaluating the performance of a computed tomographic (CT) scanner is necessary in order to ensure that a "typical" level of performance is achieved as well as providing baseline values for a program of quality assurance. Performance to be specified and tested include parameters related to (a) slice geometry, (b) patient dosage, (c) artifactual behavior and (d) contrast--detail performance. Measures of performance are defined and specified. Tests which provide for performance evaluation in these four areas are detailed and discussed.
