Revision Standard – Active. Standard test methods for the evaluation of image quality of computed tomography security-screening systems are established in this document. The quality of data for automated analysis is the primary concern. The system\u2019s ability to use this image data to automatically detect explosives or other threat materials, which is typically verified by an appropriate regulatory body, is not addressed in this standard.<\/p>\n
