Paper Abstract

We have developed an intraoperative multimodal surgical microscopy system that provides simultaneous real-time enlarged surface views and subsurface anatomic information during surgeries by integrating spectral domain optical coherence tomography (SD-OCT), optical-resolution photoacoustic microscopy (OR-PAM), and conventional surgical microscopy. By sharing the same optical path, both OCT and PAM images were simultaneously acquired. Additionally, the custom-made needle-type transducer received the generated PA signals enabling convenient surgical operation without using a water bath. Using a simple augmented device, the OCT and PAM images were projected on the view plane of the surgical microscope. To quantify the performance of our system, we measured spatial resolutions of our system. Then, three microsurgery simulation and analysis were processed: (1) ex vivo needle tracking and monitoring injection of carbon particles in biological tissues, (2) in vivo needle tracking and monitoring injection of carbon particles in tumor-bearing mice, and (3) in vivo guiding of melanoma removal in melanoma-bearing mice. The results indicate that this triple modal system is useful for intraoperative purposes, and can potentially be a vital tool in microsurgeries.
