本文报道了在不考虑呼吸影响时,应用时间平均激光条纹干涉测量法来获取在一个心动周期的各个不同时期内,由于心跳而引起胸壁变形模型的方法。该方法由测试对象的心电图控制的一个电子开关得以实现,通过对经相同处理后的全息照相底片进行逐点扫描来获取心脏各腔运动所
In this paper, a time-averaged laser fringe interferometry method is used to obtain a model of chest wall deformation due to heartbeat at different periods of a cardiac cycle without considering respiratory effects. The method is implemented by an electronic switch controlled by the electrocardiogram of the test object. The cardiac motion of each cavity is acquired by performing point-by-point scanning on the holographically processed holographic film
