A Method for Detecting Dynamic Information of Sequential Images ―Omnidirectional Gray～time Waveform and its Applications in Echocardi-ography Images

摘要

This paper presents a new method named Omnidirectional Graytime Waveform, which is used to detect dynamic information for sequential images. When applied to echocardi-ography sequential images, this method can be used to detect synchronous moving waveform of any parts from sequential images of any cardiac structures, the waveform is called Omnidirectional Gray-time echocardiography Waveform or Omnidirectional M-mode Echocardiography, which discloses the moving details of the images. This research is a significant work, because all above results hold true when the method is employed to analyze other medical images or even other moving images. An omnidirectional graytime echocardiography system and its clinical practices are introduced in this paper. As a special example, however, this method can also be put into the use of moving details understanding and dynamic information extracting-from-moving-objects composed of many sophisticated moving structures.
