To plan their operations, Guzman and his colleagues at the Department of Neurosurgery are using SpectoVR, a virtual reality system developed by Philippe Cattin and his team at the DBE. In a collaborative effort, they are further developing this system and adapting it to the clinician’s needs. Currently, the focus lies on new visualization tools inside the VR and a robot-based haptic feedback to enhance surgery simulation. The neurosurgeons are using SpectoVR also to prepare patients for surgery, and to introduce medical students to surgical practice. These applications are also continuously improved in cooperation with researchers. 

Together with Georg Rauter from the DBE, Guzman is developing novel optical systems for neurosurgical endoscopes which are to be used in the minimally invasive laser robot of the MIRACLE team, but which could also be of great benefit for traditional approaches. In the same project context, Guzman is working with Azhar Zam on systems providing measurements of the depth of cutting and tissue recognition beyond the bone – essential safety features for this technology.
