Patent application numberDescriptionPublished
20090304147X-RAY MAMMOGRAPHY/TOMOSYNTHESIS OF PATIENT'S BREAST - A breast x-ray system and method using tomosynthesis imaging in which the x-ray source generally moves away from the patient's head. The system may include an operation mode in which it additionally takes mammogram image data.12-10-2009
20090323892Breast Tomosynthesis System With Shifting Face Shield - Breast imaging using any one of a mammography system, a tomosynthesis system, or a fused system that selectively takes either or both of mammography images and tomosynthesis images, further uses a patient shield that moves closer to and further away from the patient's chest and head, between (1) an access position that facilitates the technologist's access to adjust the patient's breast while the breast is being compressed and (b) a protective position in which the shield helps protect the patient from collision with moving components and from x-ray exposure of tissue other than the tissue that is to be imaged.12-31-2009

20100260316Integrated Breast X-Ray and Molecular Imaging System - An integrated tomosynthesis/molecular breast imaging device having improved sensitivity includes tomosynthesis imaging components and molecular breast imaging components. The imaging components may be used individually or in combination to provide a system with improved sensitivity and specificity. Molecular imaging components may be smoothly advanced or withdrawn depending upon the desired imaging mode. The system supports both PET and SPECT imaging and enables SPECT collimation to be modified in accordance with image capture requirements.10-14-2010

20090003519Integrated Multi-Mode Mammography/Tomosynthesis X-Ray System And Method - 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.01-01-2009
20090135997Breast Compression For Digital Mammography, Tomosynthesis And Other Modalities - A breast x-ray imaging method and system that is particularly suited for tomosynthesis imaging but also is useful for conventional mammography. A fluid containing pillow or bag is placed between the breast and a paddle that compresses the breast against a breast platform covering an imaging device, to enhance patient comfort and provide other benefits. Alternatives include a flexible sheet compressing the breast, and a compressible foam, preferably contoured to accommodate a patient's breast.05-28-2009
20110069809INTEGRATED MULTI-MODE MAMMOGRAPHY/TOMOSYNTHESIS X-RAY SYSTEM AND METHOD - 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.03-24-2011
20110087132Needle Breast Biopsy System and Method for Use - 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.04-14-2011

Patent application numberDescriptionPublished
20090268865X-ray imaging with X-ray markers that provide adjunct information but preserve image quality - 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.10-29-2009
20100150306Mammography System And Method Employing Offset Compression Paddles, Automatic Collimation, And Retractable Anti-scatter Grid - 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.06-17-2010
20110069808X-RAY MAMMOGRAPHY WITH TOMOSYNTHESIS - 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.03-24-2011
