| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 103 === This study has developed a Phonoangiography method for using in a home-based care system to evaluating arteriovenous shunt (AVS) stenosis in hemodialysis patients. Phonoangiography is a noninvasive tool for auditing the local fluid motion in the narrowed arteries and the assessing arterial dysfunction. A bruit spectral analysis could be considered a valuable noninvasive method for quantifying the severity of vessel stenosis. A specific mock model has been set up to simplify the modeling of blood flow condition and to analyze the spectrum. It follows that a more precise relationship of phonography to stenotic lesions can be observed.
