Segmettation and Visualization of Abdominal CT Images

Abstract

One of the purposes of abominal CTimages is for the diagnosis of the diseases of colon.We present a framework for visualization of abdominal CT images.The pipe line of this framework in order is preprocessing(boundary detection),classification of the boundary points,and visulization of the area of interest.Boundary detection is carried through out a 3D.Sobel filter to find out the set of boundary points.Classification of the boundary points is to find out the connected components which is generally the wall in the interior of a colon. Visualization is to render the connected components.We present a method to generate a very wide angle perspective projection image which is to simulate the colonscopy for visulization.
