Outline of Final Research Achievements	For assessing the gastrointestinal motility, we proposed a system to measure contraction wave and volume using compound eye type endoscope. The amplitude and speed of contraction wave is used for the assessment of peristalsis, and the volume of gastrointestinal tract is used for the assessment of contraction / relaxation of tract. We constructed an algorithm to measure contraction wave and volume in three dimensions, taking into account changes in the tip position of the endoscope and evaluated the proposed system by using prototype system.
