Abstract
An apparatus and method for visualizing volume rendered images relative to a viewing vector are provided, where the apparatus includes a processor, a detection unit in signal communication with the processor for detecting occluding contours of opacified structures in the image data, and a resampling unit in signal communication with the processor for generating curved multi-planar-reformat (MPR) resamplings that follow the occluding contours of the opacified structures; and the method includes receiving a volume rendered image, including distance values and surface normals for every pixel that is opacified, gathering all opacified pixels that are orthogonal to the viewing vector into a group of occluding points, and separating the group of occluding points into individual occluding contours.
