Three-dimensional imaging in medicine development of a software library

Abstract

Advances in 3-D imaging now provide the surgeonradiologist and physician the ability to create 3-D models ofany part of the human body. The major area of clinicalapplications of 3-D imaging has been in Radiation TherapyPlanning, Computer Assisted Surgery, Brain Analysis andOrthopedics .This thesis presents a developed software library for3-D imaging on a workstation. With the volume data representedin terms of voxels , the main tasks are determinationof the object in the tomographic volume (segmentation) , determinationof the visible parts of this object at a desiredorientation and 3-D display of the resulting data on a 2-Dmonitor. The technical aspects of 3-D imaging and segmentationprocess are discussed and the results are illustratedin relation to their clinical applications. The developedsoftware library has a· modular sructure for future developments.
