摘要： According to some aspects, a method of identifying a boundary of a portion of a vasculature is provided, the vasculature comprising a geometric representation of a plurality of vessels. The method comprises logically dividing the geometric representation into a plurality of regions, determining at least one feature within each of the plurality of regions, and defining the boundary of the portion of the vasculature based, at least in part, on the at least one feature determined within each of the plurality of regions, wherein the boundary forms a volume defining a separation between inside and outside of the portion of the vasculature. According to some aspects, a method of performing vascular analysis using a geometric representation of a plurality of vessels of the vasculature is provided. The method comprises computing a boundary of a portion of the vasculature based on the geometric representation, logically dividing the geometric representation within the boundary into a plurality of regions, and analyzing at least one feature for each of the plurality of regions within the boundary.

摘要： In one aspect, a method of detecting at least on feature associated with a blood vessel in at least one image of at least one blood vessel using a matched filter adapted to respond to the at least one feature is provided. The method comprises applying a scale detection filter to selected voxels in the at least one image to determine a scale for the matched filter at each of the selected voxels, determining an orientation for the matched filter at each of the selected voxels, wherein determining the orientation is assisted by using the scale determined at each of the selected voxels, applying the matched filter at each of the selected voxels at the scale and the orientation determined at each of the selected voxels to obtain a filter response at each of the selected voxels, and analyzing the filter response at each of the selected voxels to determine if the respective voxel corresponds to the at least one feature.
摘要翻译：在一个方面，提供一种使用适于响应于至少一个特征的匹配滤波器来检测至少一个血管的至少一个图像中的至少与血管相关联的特征的方法。所述方法包括对所述至少一个图像中的选定体素应用比例检测滤波器以确定每个所选择的体素处的匹配滤波器的比例，确定每个所选择的体素处的匹配滤波器的取向，其中确定取向通过使用在每个所选择的体素中确定的比例来辅助，在每个所选择的体素处以每个所选择的体素应用匹配滤波器，并且在每个所选择的体素处确定取向以在每个所选择的体素处获得滤波器响应，以及分析每个所选择的体素处的过滤器响应，以确定相应的体素是否对应于所述至少一个特征。
