Abstract
A method for multi-planar reconstruction of digitized medical images includes providing an image volume, sampling the neighborhood about each point in a planar region and saving a color value and a depth, providing a projection plane onto which rendering rays are projected from a viewing point through said image volume, advancing sampling points along rays through the image volume, computing depths of each sampling point, determining for sampling points on rays that penetrates the planar region if a depth of said sampling point is less than the buffer depth of a corresponding point in the planar region and sampling neighborhoods of points about such sampling points, determining if sampling points are near said planar region, applying first transfer function to sample values interpolated from first volume for sampling points close to or inside the planar region, and otherwise applying second transfer function to sample values interpolated from second volume.
