Abstract

Colorectal cancer is the third most commonly diagnosed cancer, accounting for ten percent of cancer-related deaths. An imaging modality is needed with the capability to detect this cancer at an early stage. Previously, Optical Coherence Tomography (OCT) and Fluorescence Spectroscopy (FS) have been evaluated individually as diagnostic techniques for colon cancer in humans. It is hypothesized that the structural information provided by OCT and the biochemical information provided by fluorescence spectra may compliment one another and be used in combination to identify colorectal tumors.
