Abstract
An image processing apparatus for forming a high-quality surface display image at high speed is provided. From raw data input by a medical image diagnosis apparatus, gray-level volume data and binary volume data in which a region-of-interest is extracted by binarizing are obtained. The binary volume data is subjected to ray-casting and projected onto a screen. A depth image formed of pixels on the screen and a distance between the screen and the surface (surface voxel) of a display object is obtained. The coordinates of the surface voxels are calculated from the depth image. Surface normals are obtained from voxel values of the gray-level volume data and a voxel values in the vicinity, and a shaded image is formed on the basis of surface normals.
