摘要： Disclosed is an automated technique for analyzing the affected region due to an embolism in an organ. A segmented image of the organ vasculature is generated using image volume data received, for example, from a Computed Tomography (CT) machine. An embolus is then identified (either manually or automatically) within the segmented image, and the volume of the organ affected by the embolism is automatically determined. The volume of the organ affected by the embolism may be determined by computing a sub-tree within the segmented image, where the sub-tree comprises vessels that are distal to the identified embolus point. In one embodiment, the sub-tree is generated by determining a plane perpendicular to a vessel at the embolus point such that the sub-tree comprises a distal portion of the vasculature with respect to the plane. Unwanted overlapping trees are identified (e.g., by analyzing branch angles) and removed from the sub-tree. The volume of the organ affected by the embolism is determined by calculating a volume of the organ that is perfused by the sub-tree. The affected volume may be adjusted by scaling the volume based on the percentage occlusion of the partial embolus.

摘要： A multistage method, according to at least one embodiment of the invention, is disclosed for segmenting an interior region of a hollow structure in a tomographic image. In at least one embodiment of the method, portions of the image are segmented in each of at least two segmentation cycles, respectively, whilst using a substance-specific segmentation criterion. Using this procedure, the interior region of the hollow structure can be completely determined, even in the case where a plurality of substances with different imaging properties, e.g. with different attenuation properties, are present.

摘要： A method and an apparatus are disclosed for registering volume data records of the intestine which were recorded in different positions of a patient. In at least one embodiment of the method, an approximate registration is firstly performed on the basis of central lines. In a subsequent detailed registration, the approximate registration is refined on the basis of local anatomical features in the intestine, for example by using the profile of folds and/or the distance of intestinal sections from fixed points of the intestine. At least one embodiment of the method and/or the apparatus permit a more accurate registration of the at least two volume data records.
