摘要： Methods are disclosed for analyzing representations of one or more structures in the body of a subject (e.g., a human subject or other animal subject) to glean information about the health of the subject or to evaluate the subject's response to a therapy or other condition. Aspects of the invention relate to obtaining structural information from casts (e.g., vascular casts from animal models) and using the information as a reference for evaluating structures in the body of a subject. Methods are disclosed for diagnosing, staging, grading, and monitoring diseases. Methods also are disclosed for targeting treatments, monitoring the effectiveness of therapies, and/or screening or validating therapies based analyzing structures (e.g., vascular structures) in a subject and comparing them to reference structures observed in casts obtained from models (e.g., animal models) of related diseases or conditions.

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.
