We perform our weekly phantom images using an AEC mode different from the Full-Auto AEC mode that we typically use for patients. Is this acceptable toward meeting the requirement?

No. If the facility clinically uses the Full-Auto AEC mode for its standard breast patients, the weekly phantom images must be obtained using that mode. FDA requires the weekly phantom image be produced using the same clinical conditions that are used for its patients with the standard breast (compressed breast thickness of 4.2 cm, with breast tissue consisting of approximately 50% adipose (fat) tissue and 50% glandular tissue in composition). Prior to performing mammography on patients, the phantom image must achieve at least the minimum phantom score established by the accreditation body and must be within the action limits established for the three optical density requirements.
