摘要： A method and system for detecting airways in 3D lung image data is disclosed. The 3D lung image data is filtered using one or more filters based on first and second order derivatives of the CT image data. Each filter calculates a value for each voxel of the 3D lung image data, and the values from all of the filters are combined to determine a voxel score for each voxel. If the voxel score for a voxel is greater than or equal to a threshold value, the voxel is considered an airway candidate.

摘要： A branch extension method and system for segmenting airways in 3D image data is disclosed. An initial airway segmentation is obtained from the 3D image data. Terminal branches of segmented airways of the initial airway segmentation are identified. The segmentation of the terminal branches is then extended. The segmentation of the terminal branches can be extended using various segmentation techniques.

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。

摘要： A fissure detection method for lung lobe segmentation in 3D image data is disclosed. In this method, 3D lung image data is filtered using one or more filters based on at least one of planar structures coupled with vessel suppression, curvature computations, and local gradient magnitude and direction comparisons. Fissures are detected in the 3D lung image data based on the filtered 3D lung image data, and lung lobes are segmented from the 3D lung image data based on the detected fissures.
