    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.

    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: Systems and methods for reducing X-ray scatter during breast imaging, and more specifically during tomosynthesis imaging. In one embodiment, an anti-scatter grid having a plurality of septa may be configured to be positioned relative to an X-ray imaging device such that each septum of the plurality of septa extends along a direction substantially parallel to a coronal plane of a subject during imaging of the subject using the X-ray imaging device. The X-ray imaging device may be operable in a tomosynthesis mode for imaging of a breast of the subject and may include the anti-scatter grid disposed between a breast platform and the X-ray detector. The anti-scatter grid may be configured to move in a direction substantially parallel to a sagittal plane of the subject during tomosynthesis imaging.

    Abstract: A multi-modality cancer screening and diagnosis system is provided that allows cancer screening and diagnosis of a patient using at least two different and sequential three-dimensional imaging techniques without patient repositioning. The system includes a first three-dimensional image acquisition device, a second three-dimensional image acquisition device having a probe with a transmitter mounted thereon, and a positioning paddle for positioning and immobilizing an object to be imaged during the cancer screening and diagnosis procedure. The positioning paddle is designed to facilitate visualization of the breast in both three-dimensional modalities without movement of the patient, and preferably is designed to position the patient with comfort during a diagnosis procedure which uses both imaging modalities.
