<p>Volume tomographic mammography is performed with a gantry frame (206) in which a cone-beam radiation source (210) and a thin-film detector (208) are mounted. The patient (P) rests on an ergonomically designed table (202) with a hole (204) to allow one breast (B) to extend therethrough such that the gantry frame (206) surrounds that breast. The gantry frame is rotatable so that the radiation source (210) and the detector (208) move in a circular orbit around the breast (B). In addition, the gantry frame (206) is movable to describe a geometry other than a simple circle orbit, such as a circle plus one or more lines or a spiral.</p> |
