3D display of organs using CT data implementation on an IBM PC

Abstract

This thesis presents a low cost software package forthe three dimensional display of organs using an IBMmicrocomputer.First existing 3D display techniques and theirapplication in medicine are given. Then the particularalgorithm selected for implementation is described andexplanations pertinent to this specific implementation arediscussed. The boundary detection algorithm used is the onedeveloped by G.T. Herman et,al,Standard computer graphics methodsdisplaying 3D objects. A grid technique isare used introduced for whenperforming the scan conversion in orter to increase imagequality. Some of the results obtained by using mathematicalphantoms are presented and discussed. The results indicatethat this package can display high resolution images withoulantialiasing effect that is typically encountered in similarpackages. It is shown that low pass filtering is only neededin extreme cases.
