An omnidirectional M-mode echocardiography system and its clinical application.

This paper introduces the omnidirectional M-mode echocardiography (OME), which can detect dynamic information from sequential echocardiography images. The method for detecting dynamic information is based on the rebuilding of their "gray (position)-time" function Qiang L, Wenjing J, Li Z.

The system also shows a group of omnidirectional M-mode echocardiography images with synchronous ECG, which is rebuilt from 2D echocardiography images. The ECG supplies a standard time for the omnidirectional M-mode echocardiography images. The system has been applied in clinical application for 3 years and the results are good.
