摘要： The present invention relates to a device 10 for automatically identifying a part 20a, 20b of an anatomy structure comprising several parts 20a, 20b, in which anatomy structure an intervention device 21 resides. The device 10 comprises a feature extraction unit 11 and an anatomy part classification unit 13. The feature extraction unit 11 uses provided image content data ICD to extract at least one characterizing feature DS of the appearance of 10 the intervention device 21. The anatomy part classification unit 13 correlates the at least one characterizing feature DS with provided classifier data CD which are characteristic for a projection feature of the intervention device 21 viewed under certain geometry of an imaging system 30. After correlating, the anatomy part classification unit 13 determines in which part 20a, 20b of the anatomy structure comprising several parts 20a, 20b the intervention device 2115 is located.

摘要： The present invention relates to apparatus for determining an enhanced image of a vascular treatment. It is described to provide (12), a plurality of images comprising a representation of a region of interest of a vascular structure, wherein each of the plurality of images comprises image data of at least one localizing feature associated with at least one tool configured to be used in the vascular treatment and each of the plurality of images comprises image data associated with the at least one tool. Registration information for each of the images of the plurality of images is determined (14). At least two images from the plurality of images are selected (16) as a function of the registration information for each of the images. An enhanced image from the at least two images is determined (20), wherein the enhanced image provides for enhanced visibility of the at least one tool. Data representative of the enhanced image is output (24).

摘要： In cardiac roadmapping, a “roadmap”, which is typically a representation of the vasculature of a patient obtained via previously acquired data from a CT scan, is overlaid on live intervention data, showing the position of an intervention device obtained using fluoroscopy. In this way, the intervention device may be tracked inside a realistic representation of the patient. The accurate registration of the fluoroscopic image to the roadmap data is an important step, otherwise the reported live position of the intervention device would not be shown at an accurate position inside the roadmap. Registration can be performed by the injection of contrast medium. In the case of cardiac roadmapping, the small vessel diameters mean that it is possible to register intervention devices directly. However, the behavior of intervention devices in larger vessels is difficult to predict, and so device-based registration is harder to achieve in such a context. By detecting the presence of a specific intervention device and a specific vascular context, an accurate registration of the intervention device to the 3D roadmap can be provided via comparison to a library of known device configurations.

摘要： A method for artifact management in a rotational imaging system is presented. The method includes the steps of acquiring data employing a helical scanning pattern over N revolutions, where N is greater than 1, and detecting at least one artifact in the acquired data of each revolution. The method further includes segmenting the data acquired over N revolutions into N-1 data frames each bounded by at least one of the at least one artifacts.
