虽然,在超声临床诊断中,广泛地应用实时超声诊断设备以及可将帧储存动静态图象叠加在一起进行观察诊断的设备,但是尚还不能对动静态图象中的快速和复杂的动作(如心脏瓣膜的动作)进行仔细地观察。因此,对动态图象进行准确的观察是必要的。慢动作观察便是实现这种需要的方法之一。基于该目的,笔者研制了慢动作显示的超声诊断设备。本文对其原理和系统结构进行了讨论。对旧方法的改进
Although ultrasound diagnostic equipment and diagnostic imaging equipment that superimpose frames of moving and static images together for observation and diagnosis are widely used in clinical diagnosis of ultrasound, rapid and complicated actions in moving and still images Such as heart valve motion) were carefully observed. Therefore, accurate observation of dynamic images is necessary. Slow-motion observation is one way to do this. For this purpose, I developed a slow-motion ultrasound diagnostic equipment. This article discusses its principles and system structure. Improvement of the old method
