Photometric Stereo Endoscopy (PSE) as a Tool for Imaging the Rectum and Colon
The goal of this research is to assess photometric stereo endoscopy (PSE) as an endoscopic imaging technique. Specifically, topographical surface contrast reconstructed from the PSE data will be compared to conventional imaging contrast to assess if PSE provides enhanced contrast of abnormal tissue.
