Abstract

Both CT and MRI images present three-dimensional information as a series of two-dimensional slices. In conventional film sheet display, recovering the third dimension of information requires the physician to mentally reconstruct the volume. This complex process inhibits the understanding of three dimensional registration of both lesions and normal structures of surgical concern. We have developed a technique for the computerized generation of a wire-frame model from the raster image set. By using a 10242 pixel display, any three raster frames plus the wire-frame may be simultaneously displayed. Each raster frames's location is displayed on the wire-frame providing perspective clues as to the three-dimensional relationship between frames. Each raster image may be changed with real time tracking on the wire-frame model. The wire-frame may be formed from either CT or MRI images and takes less than two minutes for a standard 25 slice head series.
