| Summary: | 碩士 === 國立臺灣大學 === 電機工程學研究所 === 93 === In the ultrasound imaging process, the texture statistics are dominated by speckle formation. And it may be possible to deduce the image resolution is mainly limited to the speckle size. Besides, liver parenchyma is too complicated to decide the region of interest or sampling window size. Especially, it is hardly to capture tumor from liver cirrhosis. Therefore, how to optimize the sampling window size and extract the texture features is involving in speckle size or numbers.
Diffuse parenchymal liver disease is one of the top death causes in Taiwan. According to physical statistical theorem, observing the correlation between the feature signal to noise ratio of diffuse parenchymal liver disease and speckle size is the mainly purpose in my paper. For this reason, it is required to analyze the pathological and experiment of fabricating phantoms and on this basis we expect to analyze in vivo pathological experimenting.
