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.
摘要翻译：公开了一种用于分析由于器官栓塞引起的受影响区域的自动化技术。使用例如从计算机断层扫描（CT）机器接收的图像体积数据生成器官血管系统的分割图像。然后在分割图像中识别（手动或自动）栓塞，并自动确定受栓塞影响的器官的体积。由栓塞影响的器官的体积可以通过计算分割图像内的子树来确定，其中子树包括远离所识别的栓塞点的血管。在一个实施例中，通过确定在栓塞点处垂直于血管的平面来产生子树，使得子树相对于平面包括脉管系统的远端部分。识别不需要的重叠树（例如，通过分析分支角度）并从子树中移除。通过计算由子树灌注的器官的体积来确定受栓子影响的器官的体积。可以通过根据部分栓塞的百分比阻塞来缩放体积来调整受影响的体积。
