APPARATUS FOR CONE BEAM VOLUME COMPUTED TOMOGRAPHY MAMMOGRAPHY

摘要

A device (200) for producing a three-dimensional tomographic mammography image of a breast (B) of a patient (P), the device (200) presenting: a gantry frame (206); at least one motor (212, 214), for moving the gantry frame (206) to form a data acquisition geometry; a source (210) of radiation (C) attached to the gantry frame (206) to move with the gantry frame (206); a flat panel detector (208) attached to the gantry frame (206) to move with the gantry frame (206), the flat panel detector (208) being disposed in a path of the radiation (C); and a support (202) comprising a table (202) on which the patient (P) rests while projection images of the breast (B) are taken; the table (202) presents a through hole (204) so that the breast (B) to be scanned descends through the hole (204) in the table (202) into a breast holder (205) and the through hole (204) is disposed relative to the source (210) of radiation (C) and the flat panel detector (208) so that the breast (B) to be scanned only is disposed between the source (210) of radiation (C) and the flat panel detector (208).
