Abstract
3D visualization of CT sectional images in a video workstation with a medical imaging analysis system is very helpful to the surgeon in the selection of the optimal donor site for autogenous grafts. The sites of interest were represented on the monitor as free, interactively movable objects which could be observed three-dimensionally from all perspectives. By means of superimposition, turning, and penetration of these objects, the ideal donor site for the graft, in our examples parts from the left and right iliac crest, could be determined. An additional method for this determination is computer- assisted generation of a graft pattern from the CT data set for cases where no graftable object in the volume of interest can be found. In a special procedure a graft from biocompatible material can then be duplicated from this pattern. A reconstructive operation with 3D planning was performed on 12 patients with osseous defects in the area of the jaws and facial cranium. In the search for appropriate grafts from the patient's own body the iliac crest, with its specific volume, was selected for all patients.
