Intraoperative Volumetric Image Navigation


The original and main research program of CICAS was the creation of an interactive three-dimensional (3D) guidance system for intraoperative surgical navigation. Our laboratory developed a system, code-named Genesis, that increased the power of currently available commercial image guidance systems by providing interative three-dimensional perspective volume rendering. The significance and advantage of using this technique is that 3D models help with preoperative surgical planning and lets surgeons view the patient's data in volumetric format through their surgical tools, thus increasing visibility during surgery.

Using these techniques, surgery can be performed using the same tools and basic procedures as current minimally invasive operations, but with the added benefit of greater precision, less trauma, and an increased chance for complete treatment of the abnormality.
