A quality assurance protocol for CT scanners.
Numerous CT performance-evaluation procedures have been described in the literature, but they are generally unsuitable for routine quality-assurance (QA) testing. This report describes the QA test protocol performed at two institutions. The protocol is comprehensive and practical to perform on a routine basis. Test data demonstrate that clinically significant changes in CT scanner performance do occur, and that this protocol is capable of detecting these changes.
