A method for three-dimensional interactive segmentation, including: receiving a three-dimensional medical image of an interior volume of a patient's body; automatically performing three dimensional segmentation on the three dimensional medical image to detect and define a region of interest, wherein the performing of the three dimensional segmentation comprises automatically determining a boundary defining the region of interest; receiving from a user spatial information indicating one or more regions of disagreement in the three-dimensional medical image with respect to the determined boundary; and updating the three dimensional segmentation of the three dimensional medical image based on the spatial information received from the user, wherein the updating comprises updating the determined boundary based on the spatial information to redefine the area of interest.

Interactive segmentation

A method of analyzing a stream of imaging data is disclosed. The method comprises: for each picture-element of the data, associating a vector of features indicative of temporal intensity variation relative to baseline intensity, thereby providing a plurality of vectors. The method further comprises clustering the picture-elements according to the vectors, thereby providing a plurality of clusters, and identifying different compartments in the vasculature based on the clusters.
