The present embodiments relate to a mammograph system with a face shield. The mammography system includes an X-ray emitter head; an object table; and a face shield. The face shield is movably supported by the X-ray emitter head and is movable into at least first and second positions. In the first position, the face shield is retracted into the X-ray emitter head. In the second position, at least a portion of the face shield protrudes out of the X-ray emitter head.

Biopsy localization devices and methods made according to the invention include a bioresorbable body, such as a gelatin, polylactic acid, and / or polyglycolic acid. The bioresorbable body preferably carries a radiopaque marker. The bioresorbable body preferably swells to fill the biopsied open region. The bioresorbable body and radiopaque marker permit the biopsy site to be relocated by various techniques, including mammography and ultrasound.

A breast tomography scanner including a stationary chamber configured to hold fluid, a movable chamber within the stationary chamber configured to hold fluid, and breast scanning apparatus. Various configurations for housing the ultrasonic transducers are disclosed, along with filling and draining apparatus, leakage protections turbulence-reduction configurations and control systems.

A compression device includes a frame mountable to a mammography unit that includes a window disposed within an x-ray field of the mammography unit when the frame is mounted to the mammography unit, and a radiolucent compressible member connectable to the frame across the window for providing a compression surface within the x-ray field. For example, the compressible member may include a rigid backing member and a radiolucent pad, e.g., a gel pad, on the backing member. The backing member and frame may include tongue and groove or other connectors for connecting the compressible member to the frame. Optionally, one or more thin, radiolucent films may be removable from the compressible member, e.g., after obtaining x-rays from successive individual patients.

A portable, self-contained, electronic radioscopic imaging system uses a pulsed X-ray source, a remote X-ray sensor, and a self-contained, display and controller unit to produce, store, and / or display digital radioscopic images of an object under investigation in low voltage imaging environments such as medical applications including mammography and tissue imaging, and industrial radiography of low-density structures, or the like. The radiographic system uses an X-ray converter screen for converting impinging X-ray radiation to visible light, and thus each point impinged on the screen by X-ray radiation scintillates visible light emissions diverging from the screen. An image sensor, i.e., a CCD camera, is configured to sense the visible light from the screen. An aspheric objective lens operable with the CCD camera spatially senses visible light within a collection cone directed outwardly from the image sensor. An emission modification lens layer, e.g., a prismatic brightness enhancement film or a sprayed on transmissive layer, through which the visible light emitted from the screen is transmitted is superposed with the screen and positioned in an optical path between the aspheric lens and the screen for generally focusing the diverging visible light as a restricted cone of illumination propagating outwardly from each point impinged on the screen to increase the fraction of light directed into the collection cone of the first lens and reducing the amount of scattered visible light from the screen.
