Real-time endoscope tracking

Accurate, reproducible endoscopic reports that provide standardized data on the nature and location of GI tract lesions are critical to quality improvement in endoscopy, particularly with respect to colonoscopy performed for colorectal cancer screening and surveillance. In addition, accurate, verifiable performance-enhancing feedback is essential for training future endoscopists and for supporting continued skills enhancement for practicing endoscopists. The main objective of this project is to develop an endoscope tracking technology that measures the endoscope’s motion using integrated mechanical and optical sensing mechanisms. The Mechanical tracking is achieved by a pair of trackballs to measure real-time changes in the scope’s position and rotation during an endoscopic procedure. The cameras detect scale lines on the scope’s surface to correct accumulated trackball measurement errors. The dual modality approach provides high precision tracking and online calibration.
