| Summary: | 碩士 === 國立交通大學 === 資訊科學學系 === 84 === In this thesis we explore the reconstruction and visualization
of 2D ComputedTomography data. Traditional medical
images are usually stored intwo-dimensional photograph,
however, to view the medical image morerealistic, we show
the 3D object on the monitor by Volume Rendering. To dothis,
the characteristics of each data point( normal vector,
opacity...) haveto be extracted by the technology of image
processing. On our experimentalresults, we adopt the Cubic-
spline function and Cubic-spline convolution todo the job of
interpolation. By this way, the insufficiency problem on
thecapture of CT data is solved. And, the purpose of
reconstruction has beenachieved. Further, we apply surface
rendering technique for visualization.Finally, we render a
transparent volume and stereo-view of several data tomake it
virtually real.
