Three-dimensional Tumor Margin Detection with the Guidance of Optical Coherence Tomography and Optical Coherence Microscopy Integrated Surgical Microscope (conference Presentation)

Surgical microscopes provide clear visualization of the tissue and have been increasingly used in operating rooms. Going further from this, we developed optical coherence tomography (OCT), and optical coherence microscopy (OCM) integrated surgical microscope to offer superficial and sub-surface tissue information simultaneously. With the use of an optical switch, OCT and OCM view can be freely converted. After surgical resection of cancer with the guidance of OCT, we performed high-resolution whole cancer imaging with OCM for margin detection. Our proposed system can be a promising tool for intraoperative applications and increase the accuracy of the operation.
