Summary: | 碩士 === 國立交通大學 === 資訊科學學系 === 82 === Many area of science engineering rely on three-dimensional
digital image data generated by a image device. In medical
applications, surgeons make some diagnosis according to such
3-D data set, the CT or MRI. Here, we built a visulization
system which can help surgeons to deal with such data. And we
also expect to capture some numerical informations which may be
lost by traditional manual method in this system. In this
system, we develop a new data structure which enable us to
apply more different techniques in the volume data and
manipulate it easily. We aso use the morphological operations
to help us segmenting the volumtric data as a preprocessing
stage. Then we provide a interactive user-interface for helping
users to segment data precisely. In our concentrated area, the
medical data set, we usually can not get a high-resolution data
set in clinical applications. It will cause all traditional
algorithms of visualization can't work correctly. Thus we
develop a new algorithm to modify the original data set, such
that the modified data is suitable for traditional method.
