Digital Stereotactic Breast Biopsy Accreditation Phantom

In the past, there was not an easy way to compare the image quality of conventional and digital biopsy mammography units, because the field of view on the digital system is typically much smaller than the 24 x 30 cm field of view on conventional mammography units. In order to image the Mammographic Accreditation Phantom specified by the American College of Radiology (ACR) on the biopsy units, the user has to move the phantom to various positions in order to obtain four separate images, to be sure all objects were imaged. This is a very inconvenient, time consuming task.
