摘要： Tomosynthesis system with a rotating anode X-ray tube enabling a circular scan trajectory, wherein the X-ray tube 1 may be equipped with a large number of cathodes (21, 22) distributed around an anode. This allows to generate X-rays (41, 42) at focal spot positions (11, 12), for example evenly distributed on a for example circular line (14) on the surface (15) of an anode (10). The object (61) may be located on the (10) axis of rotation (6) of the anode at some distance to the source. For an examination, the object (61) may be exposed to X-ray beams (41, 42) generated successively on all focal spot positions (11, 12), wherein no movement of the X-ray tube 1 is necessary. The transmitted X-ray intensities may be measured by a flat panel detector (50) to achieve a reconstructed three-dimensional image data.

摘要： An apparatus for automatic selection of optimal tomography slices by executing a number of tentative segmentations using the same interactively provided in-slice seed point on some or all available tomography slices. The appropriate segmentation boundaries are then marked and the slice with the best segmentation goodness value (figure of merit) is presented to the user via a viewer. The steps are repeated when the user changes the seed point. The optimal segmentation boundary is displayed on top of a single simulated mammography image, fused from all tomography slice images.
