A stationary assembly of mains electricity (AC-powered) devices intended to produce two- or three-dimensional (3-D) diagnostic digital x-ray images of a patient’s breast using cone beam computed tomography (CBCT); it may be intended to assist a breast biopsy procedure by providing 3-D localization and guidance. It consists of an x-ray source assembly and flat panel X-ray detector (gantry), high-frequency generator, and operating console with reconstruction software; it typically includes a patient table/platform with a hole through which the hung breast may be scanned.
