| Abstract: | We provided a microcomputer-based system for analysis and displayof 3D medical images. The concrete algorithm adopted ray casting met-hod to implement 3D display in volume rendering. By combining mome-nt operator into local scene segmentation, We obtained precise surfacenormal parameter,thus making the displaying results more realistic. Theanalysis and display results of real 3D medical image data proved thesystem being useful. |
