Abstract : In this talk, I will describe the development of ultrafast 3-dimensional (3D) optical coherence tomography (OCT) imaging systems that assist surgeons during microsurgical procedures and provide intraoperative assessment. The system is based on a full-range non-uniform Fourier-Domain OCT (FD-OCT). The system was built in a CPU-GPU heterogeneous computing architecture capable of video OCT image processing. The system displays at a maximum speed of 10 volume/second for an image volume size of 160×80×1024 (X×Y×Z) pixels. We have used this system to visualize and guide a prototypical microsurgical maneuver; microvascular anastomosis of the rat femoral artery. Our preliminary experiments using 3D-OCT- guided microvascular anastomosis showed optimal visualization of the rat femoral artery (diameter < 0.8 mm), instruments, and suture material. Real-time intraoperative guidance helped facilitate precise suture placement due to optimized views of the vessel wall during anastomosis. I will also describe using the system for robotic surgical guidance that include the development of smart surgical tools. |
