Abstract

A method and apparatus for automated comparison of 3D images, such as specific shapes in images, for example, for detecting vascular changes and aneurysm growth. The method comprises an adaptive geodesic active contour (GAC) approach which can be performed in a single pass, or across multiple iterations. The method uniquely utilizes shape to identify targets in two 3D images so that images can be compared if there is any shape feature. A method is also described for iterative parameter image construction, which beneficially removes false positives. The technology is particularly well-suited for use in comparing geometric changes of aneurysms, tumors, thromboses, inflammations.
