When we breathe, chest wall and abdomen take a different motion because our respiratory muscles like rib cage and diaphragm are involved in the motion. However, common monitoring systems for respiratory motion measure a single point on body surface and thus cannot provide sufficient information about body motion. We introduce an optical monitoring system for respiratory motion using stereo CCD cameras and retro-reflective markers. It tracks three-dimensional motion of plural markers on body surface and acquire chest and abdominal motion independently. We obtained more than 30 of 20's male and female motion data using our system and analyzed their motion tendency.
