Abstract : Many people in the United States suffer from sub-arachnoidal hemorrhagescaused by the formation of cranial aneurysms. Many die even before they reach thehospital. Of the people who survive, many suffer from stroke from the emboli (bloodclot) formed near the aneurysm. In this thesis, semi-automatic segmentation techniquesare presented to extract cranial aneurysms from CTA data sets. A simple region-growingtechnique is initially used for segmenting berry type aneurysms. A sub-volume is used toextract only the aneurysm and the connecting vessels. This technique is used incombination with the morphological methods to eliminate the effects of the partialvolume effect. A bone removal technique is also presented to improve the results of thecombined region growing and morphological technique. The results of the technique areused to create a 3D model of the aneurysm. The models were used in performingcomputational fluid dynamics calculations. The technique presented in this thesis alsofacilitates viewing and analysis of the aneurysm with less manual interaction and thevisualization and quantitative results can be generated in a few minutes.,.............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
