摘要： A method and an apparatus for estimating a geometric thickness of a breast in mammography/tomosynthesis or in other x-ray procedures, by imaging markers that are in the path of x-rays passing through the imaged object. The markings can be selected to be visible or to be invisible when the composite markings/breast image is viewed in clinical settings. If desired, the contribution of the markers to the image can be removed through further processing. The resulting information can be used determining the geometric thickness of the body being x-rayed and thus setting imaging parameters that are thickness-related, and for other purposes. The method and apparatus also have application in other types of x-ray imaging.

摘要： An improved mobile X-ray unit has a counterweighted articulating X-ray tube support arm that allows positioning of an attached X-ray tube virtually without the need for moving a supporting carriage. The improved mobile X-ray unit also allows the X-ray tube to be locked to the supporting carriage during travel and the articulating X-ray arm includes several electro-magnetically actuated disk brakes capable of locking the articulating X-ray arm in a predetermined position. In the event that the carriage movement is required, the carriage may be moved by application of force on a force sensing handle engaged with the carriage by two strain gage assemblies. The strain gage assemblies provide signals to a motor drive control circuits which in turn propel two driven wheels in the direction and proportional to the force applied to the handle relative to the carriage.

摘要： A station for tomotactic-guided biopsy in prone includes a table with an aperture, and a tomosynthesis imaging system. A biopsy gun can be mounted on a stage arm assembly disposed below the table. The imaging system and stage arm assembly can be independently rotated and linearly repositioned in one or more dimensions, thereby allowing the tomotactic scan axis to be located relative to a breast being imaged.

摘要： 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 the 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 possible. An automatic x-ray collimator restricts the x-ray illumination of the breast in accordance with 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.
