First Claim
1. A method for generating a two dimensional (2D) image of a structure having at least one pixel corresponding to at least one voxel of a three dimensional (3D) image of said structure comprising:
- modeling the surface of said structure in said 3D image using a geometrical volume;
projecting normal maximum intensity projection (MIP) rays for voxels of the geometrical volume; and
generating said 2D image having said at least one pixel corresponding to said at least one voxel of said 3D image using said MIP rays.

Abstract
Disclosed is a method and apparatus for generating a two dimensional (2D) image of a structure (e.g., an organ) that has at least one pixel corresponding to at least one voxel of a three dimensional (3D) image of the structure. First, the surface of the structure in the 3D image is modeled by a geometrical volume such as an ellipsoid. Next, normal maximum intensity projection (MIP) rays are cast (i.e., projected) for voxels of the geometrical volume. The 2D image is then generated using the rays. The 2D image has at least one pixel that corresponds to at least one voxel of the 3D image.
