摘要:
The present invention relates to automatic absorption means positioning in X-ray image acquisition. To improve image quality and to optimize the radiation exposure of an object, optimal position for X-ray absorption means is provided. A first sequence (113) of X-ray images is acquired (112). For each of the images, the optimal position (115) for X-ray absorption means is determined (114). A second sequence (117) of X-ray images is associated 10 (116) with corresponding images of the first sequence. The determined optimal position for the absorption means (14) of the associated corresponding images of the first sequence (113) is selected for an acquisition of the second sequence (117). Hence, a situation-specific database with optimized positions for the absorption means is generated on behalf of the first sequence in order to provide the generated position information for the actual acquisition of a 15 second sequence of images.
