碩士 === 國立交通大學 === 生醫工程研究所 === 99 === Computerized Tomography (CT) be applied in many fields, and it is implemented by the investion of computerized tomography scanner. According to different types of scanning objects, we developed different kinds of scanners. There are several facts that affect the quality of the results of reconstruction in the scope of CT image reconstruction method, and the image enhancement is important. In this thesis, we bulid a CT scanner system with some configurable factors for the artifact construction, which would occur in reality. The system in this thesis not only simulates the artifact by some configuable factors, but also provides a solution for other verification methods to verify the quilty of the results of CT reconstruction without the requirement of the real CT scanner. This study implement texture-based volume rendering technique to build the system, due to texture-based method is well-known in the scope of direct volume rendering. In addition, the study utilized three dimention geometry transformations to implement the configurable factors. These techniques make the system to be realism.
