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： 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.
