Optical Projection Tomography of Colorectal Polyps
Colorectal cancer is the second most commonly diagnosed cancer in the UK. Screening has reduced mortality and detected large numbers of adenomas and polypoid cancers. Diagnosis of these lesions shows marked inter-observer variation using conventional 2D histopathology. Optical Projection Tomography (OPT) is a whole-mount in vitro imaging technology that produces 3D images. We are developing algorithms for quantitative analysis of OPT images of premalignant colorectal polyps, focusing on histological features of potential clinical utility. This project is in collaboration with the School of Medicine at Ninewells Hospital, Dundee (Coats, Carey) and has received funding from the Dundee Cancer Centre.
