Abstract

We present a novel sensor system based on the principles of triangulation and elastography that allows intraoperative, endoscopic and non-contact acquisition of elastic tissue properties. The sensor system consists of a 3D-printed fiber-based fringe projector, a force application system to deform the tissue, and an endoscope that records the tissue deformation at a triangulation angle. This allows reconstruction of depth maps and the elastic behavior of the specimen. The measurement system is designed to be used during cystoscopy or transurethral bladder tumor resection and can be integrated into the working channel of a commercially available cystoscope.
