20090097615 | DEVICE AND METHOD FOR PROCESSING AND PRESENTATION OF X-RAY IMAGES - In a device and method for processing and presenting x-ray images, an x-ray image of a subject is acquired with an x-ray acquisition cone simultaneously with the acquisition of an optical exposure of the examination subject with an optical acquisition cone that is congruent with the x-ray acquisition cone. The subject in the optical exposure is subjected to segmentation and/or edge extraction, and the extracted optical exposure and the x-ray image are additively combined so that the subject edges from the optical exposure are inserted into the x-ray image. | 04-16-2009 |
20090190819 | X-RAY ACQUISITION METHOD AND DEVICE FOR STEREOTACTIC BIOPSY - 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 ( | 07-30-2009 |
20090207969 | TOMOSYNTHETIC IMAGE RECONSTRUCTION METHOD AND APPARATUS - To generate a tomosynthetic 3D x-ray image composed of a number of slice images, a tomosynthetic 3D intermediate image composed of a number of slice images is reconstructed from 2D projection images that have not been noise-filtered. The microcalcium regions contained in these slice images are segmented, and one or more subject slice images relevant to these microcalcium voxels are determined for each microcalcium region. The microcalcium voxels belonging to the segmented microcalcium region in this subject slice image or in these subject slice images are projected forwards in the 2D projection images, and the microcalcium pixels associated with these microcalcium voxels are marked in the 2D projection images. Noise-filtered 2D projection images are subsequently generated by subjecting the microcalcium pixels of the 2D projection images to no noise filtering or a noise filtering that leads to a noise reduction reduced relative to the remaining image regions. The tomosynthetic 3D x-ray image is then calculated from the 2D projection images that have been noise-filtered in this manner. | 08-20-2009 |
20100014635 | METHOD AND MEDICAL SYSTEM FOR ASSISTING A MEDICAL MEASURE IMPLEMENTED BY THE MEDICAL SYSTEM - In a method and a medical installation for assisting in a medical measure implemented by a medical device, a lighting element generates light that uniformly illuminates the medical device or its environment, the illumination being designed to reduce stress on the part of a patient undergoing the medical measure. | 01-21-2010 |
20100054402 | METHOD FOR POSITIONING THE BREAST FOR A BIOPSY IN A MAMMOGRAPHY DEVICE, AND MAMMOGRAPHY DEVICE TO IMPLEMENT THE METHOD - 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. | 03-04-2010 |
20100286802 | METHOD TO OPERATE AN IMAGING SYSTEM, AND IMAGING SYSTEM - In an imaging system having a number of subsystems and a control device that controls the subsystems in a coordinated manner to implement a measurement sequence and an operating method therefor, sequence control data that define different functional sub-sequences of the measurement sequence are transmitted to the control device. Different active volumes are associated with the functional sub-sequences. In addition to the sequence control data, active volume position data are provided to the control device that define bearing and extent of the active volumes associated with the different functional sub-sequences. Control signals to implement the measurement sequence for the different subsystems are generated automatically by the control device based on the sequence control data and the active volume position data so that the individual functional sub-sequences are locally optimized at least with regard to a sub-region of their associated active volume. | 11-11-2010 |
20100321404 | METHOD AND DEVICE FOR DISPLAYING AN X-RAY IMAGE RECORDED IN THE COURSE OF MAMMOGRAPHY - In a method and apparatus for displaying an x-ray image acquired in a mammographic examination wherein the breast was compressed to a compression thickness, a breast area of the breast in an image area of the x-ray image is determined, and the glandular density of the breast area is determined from brightness levels of the x-ray image in the image area and from the compression thickness. A value that characterizes the glandular density is displayed together with the x-ray image. | 12-23-2010 |
20110087098 | MAMMOGRAPHY SYSTEM AND METHOD FOR SONOGRAPHIC AND RADIOGRAPHIC EXAMINATION OF A BREAST - A mammography device for examining a breast has a support plate and a compression plate, between which the breast is positioned and compressed during a radiographic examination. An ultrasound transducer for obtaining a sonogram of the breast is brought into direct contact with the breast either by temporary mounting in one of the support plate or the compression plate or by exchanging one of the compression plate or the support plate with another plate that contains the ultrasound transducer. | 04-14-2011 |
20120020455 | DEVICE AND METHOD FOR A MAMMOGRAPHY APPARATUS - The maximum possible vertices for a trajectory are determined with a device for mammography and an associated method, so that the subject to be exposed can be completely imaged on the detector in x-ray acquisitions. | 01-26-2012 |
20120022358 | METHOD AND MAMMOGRAPHY APPARATUS FOR IMAGE-ASSISTED BIOPSY EXTRACTION - In a device and associated method, images of a biopsy unit in x-ray images for a second volume set are determined and replaced with x-ray image data of corresponding x-ray images for a first volume set, to produce a revised second volume set. | 01-26-2012 |
20120022401 | DEVICE FOR TISSUE EXTRACTION - In a device for tissue extraction from a breast, a needle mount accommodating a biopsy needle can be placed by a connection element such that no regions of the breast that are to be examined by x-rays are occluded by parts of the device during an x-ray image acquisition. | 01-26-2012 |
20120157819 | IMAGING METHOD AND IMAGING DEVICE FOR DISPLAYING DECOMPRESSED VIEWS OF A TISSUE REGION - A method visualizes a tissue region. The method includes the following steps: inserting the tissue region into the capturing region of a first imaging modality, with the tissue region assuming a first shape; capturing the interior of the tissue region by the first imaging modality; establishing a first image volume of the interior of the tissue region when it assumes the first shape; and first transforming of the first image volume into a second image volume, which represents a surface and interior regions of the tissue when the tissue region assumes a second shape. | 06-21-2012 |
