摘要：
System for analyzing a vascular structure. The system includes an initialization module that is configured to analyze a slice of a VOI that includes a main vessel of the vascular structure to position first and second luminal models in the lumen. Each of the first and second luminal models represents at least a portion of a cross-sectional shape of the lumen and has a location and a dimension in the slice. The system also includes a tracking module that is configured to determine the locations and the dimensions of the first and second luminal models in subsequent slices. For a designated slice, the locations and the dimensions of the first and second luminal models of the designated slice are based on the locations and the dimensions of the first and second luminal models, respectively, in a prior slice and also the image data of the designated slice.
