Abstract
The aspects of the present disclosure are directed to a method and system for producing tomosynthesis images of a breast specimen with the capability of attaining images with geometric magnification. In one embodiment, an x-ray source delivers x-rays through a specimen of excised tissue and forms an image at a digital x-ray detector with the resultant image enlarging as the specimen is moved closer to the x-ray source. Multiple x-ray images are taken as the x-ray source moves relative to the stationary breast specimen. The source may travel substantially along a path while the detector remains stationary throughout and the source remains substantially equidistant from the specimen platform. The set of x-ray image data taken at the different points are combined to form a tomosynthesis image that can be viewed in different formats, alone or as an adjunct to conventional specimen radiography.
