Abstract

NIR optical tomography in endoscopic imaging geometry is a novel technique for noninvasive tissue-specific cancer detection in internal organs. The arrangement of source and fiber detection system is an important aspect in maximizing depth sensitivity in particular for axial imaging. This study demonstrates that using multiple arrays of fibers within an elliptic shaped probe increases depth resolution as compared to single array of fibers within a cylindrical shaped probe.
