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.
为确保达到“典型”的性能水平并为质量保证计划提供基线值，指定并评估计算机断层扫描（CT）扫描仪的性能是必要的。需要指定和测试的性能包括与以下方面相关的参数：（a）切片几何形状，（b）患者剂量，（c）伪影行为，以及（d）对比度 - 细节性能。定义并指定了性能测量方法。详细介绍并讨论了在这四个领域进行性能评估的测试。
