Photometric Stereo Endoscopy (PSE) as a Tool for Imaging the Rectum and Colon

Completed · Not applicable

Conditions studied: Colonic Polyps

In brief

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.
