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.

摘要： According to an exemplary embodiment of the present invention, a cardiac roadmapping technique is provided, that does not rely on the prerequisite of a phase-centric pairing of the angiogram and life images. Instead, both the pairing and accurate registration of the images are combined within a single operation, for example by using a multi-device map. This may provide for robust and precise cardiac roadmapping.

摘要： X-ray images are projective, meaning that the 3D geometry is flattened along projection lines going from the source to the detector. In particular procedures, such as mapping or ablation, the interventional instrument lies on the wall of the organ. Using a 3D segmentation of this organ registered to the x-ray, the instrument necessarily lies on the intersection of this surface with its projection line. The line and the surface typically intersect with a segmentation surface at a discrete number of points (typically 2 for shapes such as the anterior of the LA). One then has just to disambiguate between these different possible locations to determine the exact location of the instrument. In this invention, we propose to use the apparent width of the instrument measured in x-ray images to accomplish this task.

摘要： Cardiac roadmapping consists in correctly overlaying a vessel map sequence derived from an angiogram acquisition onto a fluoroscopy sequence used during PTCA intervention. This enhanced fluoroscopy sequence however suffers from several drawbacks such as breathing motion, high noise level, and most of all suboptimal contrast-enhanced mask due to segmentation defaults. This invention proposes to reverse the process and to locally overlay the intervention device as seen in fluoroscopy onto an optimal contrast-enhanced image of a corresponding cycle. This drastically reduces or suppresses the breathing motion, it provides the high image quality standard of angiograms, and avoids segmentation defaults. This proposal could lead to a brand new navigation practice in PCI procedures.

摘要： A medical viewing system with an X-ray image acquisition device for acquiring angiograms and interventional live images of vessels is adapted for generating a region of interest border into which an object referenced by an object-based registration process must extend in order to achieve an accurate registration of vessel trees extracted from the angiogram and the live images. The region of interest border is then overlaid onto the vessel tree images and the live images. The medical viewing system reminds the person accomplishing the intervention of the importance of pushing the object far enough into the image, while being discrete enough to be ignored if preferred, thus yielding in a reliable and precise road mapping processing.
