Abstract
A system and corresponding method for organ wall analysis are provided, the system including a processor, an imaging adapter in signal communication with the processor for receiving organ scan data indicative of an organ, a distance mapping unit in signal communication with the processor for providing a three-dimensional distance map of a segmented outer surface of an organ, and a ray-casting unit in signal communication with the processor for providing a maximum intensity projection substantially normal to the segmented outer surface for each of a plurality of rays, and for forming a ray collection by casting each of the plurality of rays from a center of the organ through the respective maximum intensity projection to the segmented outer surface; and the corresponding method including providing a three-dimensional distance map of a segmented outer surface of an organ, providing a maximum intensity projection substantially normal to the segmented outer surface for each of a plurality of rays, and forming a ray collection by casting each of the plurality of rays from a center of the organ through the respective MIP to the segmented outer surface.
