Revision History



Important: All items in bold in the Technique Parameters and Anatomic Coverage sections below are required to successfully achieve accreditation. CTDIvol information is required for each study. Either include a screen save of the dose with the images, or enter the dose as displayed by the scanner in the Clinical Test Image Data Sheet. Please be aware, special attention must be paid to scanner output (CTDIvol) for pediatric studies. The facility will not receive a pass if the radiation dose is perceived to be too high, regardless of whether the rest of the CT study conforms to satisfactory criteria.
