Abstract

Commercial telerobotic surgery systems for soft tissue surgery are generally limited to visual imaging, though it is possible to view picture-in-picture visualization of another workstation. However, it is not easy to correlate such information with the endoscopic view since it may not relate to the surface visible in the visual endoscopic images. As critical surfaces, as well as surgical targets often lie subsurface, a range of techniques (e.g. ultrasound and near infrared imaging) and registration methods have been investigated as robotic surgery gains popularity. While investigation of nerves, blood vessels, and tumors has received prior attention, we present a system for real-time multimodal image registration that focuses on the visualization of the urinary tract. By providing an accurate registration between stereo video images and a near-infrared imager, we aim to enhance surgical awareness and make critical uretary tasks such as mobilization of the ureters easier. Experiments with a prototype imager using a phantom, and in vivo experiments using a prototype Hamamatsu Photodynamic Eye (PDE) imager together with the da Vinci stereo endoscope are presented.
