  • Patent number: 8184770
    Abstract: In a method and an associated device for generation of digital x-ray image exposures of an examination subject with an x-ray source and a digital x-ray detector for a stereotactic biopsy, wherein, for one or more x-ray image acquisitions of the examination subject with a biopsy device, acquisition and image processing parameters are used that have been determined from an x-ray image exposure of the examination subject without the biopsy device (7). The influences that are disruptive for an optimal x-ray image, for example of metallic biopsy devices, can thereby be avoided.
    Type: Grant

  • Patent number: 7974378
    Abstract: In a method and a mammography device, a virtual mask is created from an x-ray image of the breast for positioning the breast for a biopsy. The mask reproduces the image region covered by the breast tissue. A region targeted for the biopsy, and located within the breast tissue, is marked in the mask. The breast is then positioned for the biopsy in the mammography device between a support plate and a compression plate, the compression plate being provided with a recess for introducing the biopsy instrument therethrough. The mask and the compression plate are superimposed to cause the marked region to be located within this recess. The breast is then moved until the position and the contour thereof substantially coincide with the position and contour of the mask.
