1. A method for measuring shapes in thick multi-planar reformatted (MPR) digital images, comprising the steps of:

  • identifying a shape in a digital MPR image;

    scan-converting points corresponding to the identified shape on a starting plane of an MPR slab in an image volume from which the MPR was obtained to generate a plurality of starting points for the identified shape;

    calculating an end point in the MPR slab corresponding to each starting point;

    propagating a ray from each starting point to each corresponding end point;

    accumulating samples along each ray; and

    computing a desired measurement value from the accumulated samples after reaching the end point for all rays.
