Hyperspectral Imaging for In Vivo Detection of Trachea Tissue

William Yardley Christensen

Abstract


The purpose of this project was to build a device that could detect tracheal and esophageal tissues to assist in tracheal intubation procedures. The devices built focused on filtering specific spectra of reflected light. The first device projected white light from LEDs onto the tissue samples with the reflected light being measured by photodiodes after passing through optical filters. The second device projected white light from LEDs and captured and transmitted the reflected light via optical fiber to photodiodes with similar optical filters mounted on them. Although a delay in receiving the tissue caused the results for the first device to be inconclusive, the second device detected trachea tissue with 100% accuracy.
