摘　　要：用Simulink中的And、Bitwise Operator、Switch、Relation operation和sum of elements等模块对心脏二尖瓣偏心反流视频图像进行了分析。提取出了视频图像中心脏二尖瓣偏心反流部分,并计算出每一帧图像中反流部分的面积。给出了六幅曲线图,其中每一幅曲线图是同一时相的每隔5度的二尖瓣偏心反流面积曲线图。本文的分析对心脏疾病的临床诊断和治疗有重要意义。Using modules of the and, bitwese operator, switch, relation operation and sum of elements in Simulink tool, this paper analyzed the video images of mitral eccentric regurgitation, picked upthe mitral eccentric regurgitation of the video images and figured out the area of regurgitation in every image frame.Six graphs were presented and each graph was the graph of the areas of the mitral eccentric regurgitation after an interval of 5 degrees in the same phase.The analyzing was very important to cljnic diagnose and cure of heart attack.
