Sensor for Spatial Imaging of Colonoscopes

This project will develop a simple, easy to use system which projects a three dimensional imageof the position of a colonoscope onto a video screen next to the endoscopic image. Goals for Phase Iare to 1) design and build a prototype sensor instrument which determines the position and posture ofa colonoscope during operation, 2) develop the computer software needed to display the threedimensional image of the scope on a video screen, and 3) evaluate instrument performance underconditions which simulate the in vivo environment. This system will play a major role in guidingcolonoscopes through the colon to the cecum. It will increase the efficiency of colonoscopy, save time,and possibly decrease morbidity due to the procedure by reducing excess looping in the colon, asignificant factor in colonic perforation. This will lead to the specifications for a commercial endoscopicimage detector instrument.
