Abstract
Optical coherence tomography (OCT) provides high-resolution, non-invasive imaging of the rectum. Extending the imaging range would allow a thorough examination, including detecting surface polyps, tumors, and their infiltration depth. This study combines a gradient index (GRIN) fiber for extended-range imaging and a single-mode fiber for standard-resolution imaging within a rigid rectoscope, using a 3.2 MHz-OCT system. A fiber optic MEMS switch enables easy transitions between both modes in real-time. The extended imaging range enables deeper structure visualizations, while the standard resolution offers improved image quality for direct contact assessments, highlighting the system's adaptability and enhanced diagnostic capabilities.
