| Summary: | 碩士 === 元智大學 === 資訊管理學系 === 98 === This study propose a computer-aided system to provide the motion analysis and assessment of cardiac function in catheterization ventriculography. First, we use the block matching method to segment the coarse contour of left ventricular region. Then, morphological operations were used to refine the contour. Secondly, a two step fuzzy logic system was used to identify the direction of heart motion. The Doppler ultrasonography representation was used to present a more intuitive and objective interpretation of cardiac information. Finally, some of the parameters such as Ejection Fraction and slope variation of ventricular are used to evaluate the cardiac function. Experimental results show that the proposed method can provide an effective motion analysis and assessment of cardiac function in catheterization ventriculography. Meanwhile, it can be further as the computer aided diagnosis system (CAD) for differential diagnosis in the future.
