The authors identified the origin of a high-density artifact with mammography film. An acrylic ramp phantom (thickness, 0-7 cm) was used to create a continuously variable radiation exposure. A perturbation in the curve of optical density versus position along the ramp was observed. Development of the film with the emulsion side down eliminated this artifact.
