Abstract: A method and system for producing tomosynthetic images of a patient's breast. An x-ray source that delivers x-rays through a breast immobilized and compressed between a compression paddle and a breast platform and form an image at a digital x-ray receptor panel. Multiple x-ray images are taken as the x-ray source and the receptor move relative to the immobilized breast. In one preferred embodiment, the x-ray source travels from ?15° to +15°. The source can travel in an arc around the breast while the receptor travels linearly while remaining parallel and at the same distance from the breast platform. The sets of x-ray image data taken at different angles are combined to form tomosynthetic images that can be viewed in different formats, alone or as an adjunct to conventional mammograms.

Abstract: A specimen radiography system may include a controller and a cabinet. The cabinet may include an x-ray source, an x-ray detector, and a specimen drawer disposed between the x-ray source and the x-ray detector. The specimen drawer may be automatically positionable along a vertical axis between the x-ray source and the x-ray detector.

Abstract: A breast compression paddle includes a bracket, a rigid substrate, and a foam compressive element. The bracket removably secures the breast compression paddle to an imaging system. The rigid substrate is secured to the bracket and includes a first edge and a second edge disposed opposite the first edge. The foam compressive element is slidably secured to the rigid substrate.

Abstract: An apparatus for holding a breast compression paddle, includes a base, a lip connected to and extending substantially orthogonal from the base, an arm connected to and extending substantially orthogonal from the base and disposed substantially parallel to the lip, and a tine connected to and extending at an angle to the arm. The lip defines a lip plane, and the tine is oriented towards the lip plane. The apparatus is configured to hold and support a compression paddle.

Abstract: A system for multi-mode breast x-ray imaging which comprises a compression arm assembly for compressing and immobilizing a breast for x-ray imaging, an x-ray tube assembly, and an x-ray image receptor is provided. The system is configured for a plurality of imaging protocols and modes.

Abstract: Systems and methods for breast x-ray tomosynthesis that enhance spatial resolution in the direction in which the breast is flattened for examination. In addition to x-ray data acquisition of 2D projection tomosynthesis images ETp1 over a shorter source trajectory similar to known breast tomosynthesis, supplemental 2D images ETp2 are taken over a longer source trajectory and the two sets of projection images are processed into breast slice images ETr that exhibit enhanced spatial resolution, including in the thickness direction of the breast. Additional features include breast CT of an upright patient's flattened breast, multi-mode tomosynthesis, and shielding the patient from moving equipment.

Abstract: A compression arm device for compressing a breast in an imaging system with a compression paddle. The compression arm device includes a drive for moving the compression paddle towards the breast such that the drive provides a variable resistance during a contact of the compression paddle with the breast.

Abstract: A mammographic imaging system is optimized for use with a single fixed size flat panel digital image receptor. It accommodates compression devices (paddles) of varying sizes, and positions them properly in a field of view of the image receptor. When a compression paddle with size smaller than the field of view of the image receptor is used, the compression paddle can be shifted laterally in the direction parallel to the chest wall, so as to facilitate different views of different size breasts, and permit the image receptor to image as much of the desired tissue as passible. An automatic X-ray collimator restricts the X-ray illumination of the breast in accordance with the compression paddle size and location in the field of view. An anti-scatter grid, mounted inside the image receptor enclosure, just below the top cover of the enclosure, can be retracted out of the field of view of the image receptor for use in magnification imaging.

Abstract: A tilted needle biopsy assembly is provided for mounting on an x-ray system. Because the biopsy needle is angled relative to at least one of the detector and the x-ray source, x-ray imaging may be performed during the biopsy procedure without interference by the biopsy device. The angled biopsy needle additionally allows improved access to the axilla and chest wall of the patient. The stereotactic biopsy device of the present invention may be coupled to any x-ray system, whether upright or prone, including but not limited to mammography systems, tomosynthesis systems, and combination mammography/tomosynthesis systems. The system flexibly supports the use of any mode of image capture (i.e., scout, two dimensional mammogram, three-dimensional reconstructed volume) for either or both target visualization and target localization. With such an arrangement, a needle biopsy assembly having improved patient coverage is provided for use with a variety of different x-ray imaging platforms.
