超声波最早用于军事及工业领域,在医学界普遍使用不过有一二十年的历史。在某些方面,超声心动图目前已代替了带有创伤性质的心脏导管检查术。 超声波在心脏的传播过程中,可在各个部位发生良好的反射,并显示在特制的扫描器上。随着心脏的跳动,其反射光线做同步摆动,经过处理之后,各光点的活动轨迹被展开,因而能显示心脏各部位结构的厚度、距离、活动强度以及方向,从而有助于对心脏疾
Ultrasound was first used in military and industrial fields, but generally used in the medical profession for a decade or two. In some aspects, echocardiography has now replaced traumatic cardiac catheterization. Ultrasound in the heart of the spread of the process, can occur in all parts of a good reflection, and displayed in a special scanner. With the beating of the heart, the reflected light is synchronized to swing. After processing, the trajectory of each spot is unfolded, thus showing the thickness, distance, activity intensity and direction of the structure of each part of the heart, thereby contributing to heart disease
