摘要： There is a method and a corresponding system for optimizing X-ray imaging during a mammographic examination. In order to provide an optimization of X-ray imaging in a first step (SOI) a breast (7) is compressed between a support plate (5) and a compression plate (3). In a next step (S03), a force-height curve (13) is acquired during compression. Then, in a further step (S05) an elasticity value of the breast (7) is determined radiation-free based on the force-height curve (13). In a further step (S07), a parameter of an X-ray imaging system is optimized based on the determined glandularity (g). As the glandularity (g) of a breast may influence the attenuation of X- rays, the personalized setting of the parameters of the X-ray imaging system may greatly enhance the image quality.

摘要： Minimally-invasive spinal inventions are often performed using fluoroscopic imaging methods, which can give a real-time impression of the location of a surgical instrument, at the expense of a small field of view. When operating on a spinal column, a small field of view can be a problem, because a medical professional is left with no reference vertebra in the fluoroscopy image, from which to identify a vertebra, which is the subject of the intervention. Identifying contiguous vertebrae is difficult because such contiguous vertebrae are similar in shape. However, characteristic features, which differentiate one vertebra from other vertebra, and which are visible in the fluoroscopic view, may be used to provide a reference.

摘要： A method and related apparatus (VS) for synthetic projection images, in particular synthetic 2D mammograms (S) formed from a 3D image volume T made up of slices (SL).It is proposed to compute a forward projection (FP) using a weighted average function that is implemented by a filter (FL). The filter function (FL) is configured such that that voxels in a slice with maximum sharpness are assigned highest weights thereby avoiding blurring by averaging with structurally less relevant slices.

摘要： The invention relates to peripheral equalization during a mammography X-ray examination. High contrast tissue pixel values are removed from the background estimate by finding the minimum intensity values of the pixel located in the neighbourhood, which have approximately the same distance to the skin line. Thus, high attenuating pixel values may be removed from the estimate and replaced by lower attenuating tissue pixel values. After a minimum filtration, a conventional peripheral equalization is performed. This may result in less overshoots and intensity values for higher attenuating structures in the peripheral region may become more consistent with intensity values for higher attenuating structures in the fully compressed region.
摘要翻译：本发明涉及乳房X线照相X线检查期间的外周均衡。通过找到位于邻域的像素的最小强度值，其具有与皮肤线大致相同的距离，从背景估计中去除高对比度组织像素值。因此，可以从估计中去除高衰减像素值，并由较低衰减的组织像素值代替。在最小过滤之后，执行传统的外围均衡。这可能导致在周边区域中较高衰减结构的较少过冲和强度值可能变得与完全压缩区域中较高衰减结构的强度值更一致。
