適用范圍：This part of IEC 61223 provides assistance in performing CONSTANCY TESTS on a CT SCANNER.It applies to those components of CT SCANNERS which influence the image quality, PATIENTdose and positioning.This standard– defines the essential parameters which describe the performance of CT SCANNERS withregard to image quality, PATIENT dose and positioning; the list of parameters to be testedcan be found in section 4.5;– defines the methods of testing the essential parameters;– provides criteria to be applied in the evaluation of data for compliance with the tolerancesof the parameters specified by the ACCOMPANYING DOCUMENTS and with respect to BASELINEVALUES.These methods rely on non-invasive measurements, using appropriate test equipment,performed to ensure that the functional performance of EQUIPMENT meets ESTABLISHEDCRITERIA or to enable the early recognition of changes in the properties of components of theEQUIPMENT.The aim is to verify compliance with specifications affecting the image quality, PATIENT doseand PATIENT positioning.It is not intended to consider:– aspects of mechanical and electrical safety nor– aspects of mechanical, electrical and software performance, unless they are essential forperforming the CONSTANCY TESTS and directly affect image quality, PATIENT dose andpositioning.
