Objective To confirm clinical significance of wall motion velocity and acceleration measured by LEJ-1 omni-directional M-mode echocardiography (OME).
目的证实LEJ - 1型全方向m -型超声心动图测量心室壁运动速度与加速度的临床意义。
2
Two-dimensional interpolation method is discussed to reduce the error of distance calibration which is caused by the omni-directional machining accuracy.
在距离标定中，本文提出的二维插值法减小了全景反射镜面因加工精度不高而带来的距离标定误差。
