Abstract
Optical technologies are widely used for tissue sensing purposes, however maneuvering conventional probe designs with flat-tipped fibers in narrow spaces can be challenging, such as in pelvic colorectal cancer surgery. In this study, a compact side-firing fiber probe was developed for tissue discrimination during colorectal cancer surgery using diffuse reflectance spectroscopy. The light behavior was compared to flat-tipped fibers using both Monte Carlo simulations and the tissue classification performance was examined using freshly excised colorectal cancer specimens. Using the developed probe and classification algorithm, we achieved an accuracy of 0.92 for the discrimination of colorectal tumor tissue from healthy tissue.
