1. Center the phantom at the chest wall edge of the image receptor. Place the compression paddle in
contact with the phantom to secure it.
2. If phototiming is available, make a phototimed exposure.
3. If the unit does not have phototiming, manually select the kVp and mAs routinely used to
radiograph the Mammographic Accreditation Phantom (Model 18-220).
4. Make the exposure.
5. Analyze the image on the monitor.
6. To pass accreditation with the Digital Mammography Evaluation Phantom, you must be able to see
3 fibers,
3 groups of specks, and 2.5 masses.
7. Record your image on disk or film.
8. In accordance with the American College of Radiology, this test should be done weekly.
