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

Abstract

This thesis presents a low cost software package for the three dimensional display of organs using an IBM microcomputer.First existing 3D display techniques and their application in medicine are given. Then the particular algorithm selected for implementation is described and explanations pertinent to this specific implementation are discussed. The boundary detection algorithm used is the one developed by G.T. Herman et,al, Standard computer graphics methods displaying 3D objects. A grid technique is are used introduced for when performing the scan conversion in orter to increase image quality. Some of the results obtained by using mathematical phantoms are presented and discussed. The results indicate that this package can display high resolution images withoul antialiasing effect that is typically encountered in similer packages. It is shown that low pass filtering is only needed in extreme cases.
