Abstract
Colonoscopy is the most widely prescribed colonic imaging method for the clinical surveillance of colorectal cancer for the detection of adenomatous polyps. However, some adenomas appear diminutive and flat, making them difficult to discriminate from non-neoplastic tissue even for the most experienced colonoscopists. We report here an optical system for performing excitation resolved visible and near-infrared autofluorescence imaging and hyperspectral imaging for the accurate distinction between neoplastic and non-neoplastic tissue. This is demonstrated on ex vivo colorectal tissues using our multimodal imaging system, which has potential applications for the in vivo endoscopic imaging and diagnosis of colorectal cancer tissue.
