一、图像诊断法的进步1.超声波检查法超声心动图是从M 型超声开始的,以后发展为B 型超声,现在又发展到多普勒法。由于超声断层法可以提供心脏结构的位置关系及心脏容积、壁厚、心肌局部运动等重要情报,所以是心瓣膜病、心肌病、缺血性心脏病、心包疾病以及先天性心脏病等各种心脏病诊治上不可缺少的手段。此法和情报处理工程技术的进步相辅相成,现在已在心功能定量分析方面广泛利用。超声多普勒法可以观察过去用超声心动图不能得到的心腔内血流状态,因而近年有
First, the progress of image diagnostic 1. Ultrasound echocardiography is from the M-type ultrasound began to develop into B-mode ultrasound, and now it has developed to Doppler. Because the ultrasonic tomography can provide the heart structure of the positional relationship and heart volume, wall thickness, myocardial movement and other important intelligence, it is valvular heart disease, cardiomyopathy, ischemic heart disease, pericardial disease and congenital heart disease and other Heart disease diagnosis and treatment indispensable means. The progress of this method and information processing engineering complement each other and is now widely used in the quantitative analysis of cardiac function. Ultrasound Doppler method can be observed in the past with echocardiography can not be obtained intracardiac blood flow state, which in recent years
