Abstract

A system for extracting flow information from a dynamic volumetric angiography dataset is configured for segmenting (202) a vasculature structure by labeling certain voxels of the dynamic volumetric angiography dataset as belonging to the vasculature. For each of a plurality of the labeled voxels, (203) a voxel time value is calculated indicative of a time when a time sequence of a voxel of the dynamic volumetric angiography dataset satisfies a certain predetermined condition. A histogram is calculated (204) of the calculated voxel time values. The system determines (205) a time window having a lower voxel time value and an upper voxel time value, by fitting a model to the histogram, wherein the model defines the time window in terms of certain predetermined features of the histogram. The system associates (206) a first color to the lower voxel time value, and a second color to the upper voxel time value.
