Computer Vision News - April 2018

We had the chance to test ourselves one of the da Vinci systems, which - elaborates M. Sc. student Keith Tsang - when it is given realistic augmented reality, it offers the surgeon valuable information during the surgery procedure. It does that by registering MR imaging (which is often taken days or weeks before the intervention) by real-time ultrasound imaging (which is not very effective in detecting tumor pathologies). Registration of the two modalities is what offers the best vision of the interested region. Beforehand, the systems undergoes a calibration process with the tools of the surgeon. “ This is an ongoing study - adds postdoctoral fellow Golnoosh Samei - with the Vancouver General Hospital and one of the surgeons there who performs prostatectomies. He has already taken the system in the operating room, since it does not interfere with the regular surgery procedure. ” “ Much of the design and specifications comes from surgeons themselves - concludes Abolmaesumi - and the objective of our work is to provide not just registration and segmentation but a full system functioning from A to Z. This makes the distinctiveness of our lab. It is very uncommon to find a laboratory working on such a wide spectrum: from the very beginning of a device design to actually integrating the system. ” 19 RCL - UBC Vancouver Computer Vision News “This makes the distinctiveness of our laboratory.
