Abstract: Minimally invasive surgery exhibits many advantages compared to opensurgery, but it is limited in safety and efficiency by contemporary laparoscopes due totheir non-stationary nature and inherently exhibited trade-off between resolution and instantaneous field of view (FOV). We have been developing a multi-resolution foveated laparoscope (MRFL) technology aiming to address these limitations. The MRFL is a stationary dual-view imaging device with optical scanning and zooming capabilities. It is designed to simultaneously capture and display a zoomed view and supplemental wide view of the surgical field. Optical zooming and panning capabilities facilitate repositioning of the zoomed view without physically moving the system. In this talk, I will provide an overview of the technology development, present assessment studies performed with clinicians using both dry-lab surgical training box and in-vivo porcine surgical studies, and discuss findings and future work.
Bio: Dr. Hong Hua, Fellow of NAI (National Academy of Inventors), SPIE and OSA, is currently a professor with the James C. Wyant College of Optical Sciences (OSC), at The University of Arizona. She has over 25 years of experience designing and developing near-eye display technologies for virtual reality and augmented reality applications as well as microscopic and endoscopic imaging systems for medicine.
