8 February 2008 Sound and volumetric workflow feedback during image guided neurosurgery

To improve the efficacy of tumor resection in image guided neurosurgery, two new types of feedback were investigated. Firstly, sound feedback to give the surgeons a warning signal when the instrument tip approaches normal/non-planned brain tissue. Secondly, workflow feedback by logging and tagging all instrument positions in image space. Results from laboratory and clinic suggest that sound feedback seems to be useful but needs more fine tuning before it will be practical for clinical use. Workflow feedback, on the other hand, appears to be a simple, cheap and efficient method to give the surgeon insight in the progress of resection, to log locations of interest, and to give insight in brain deformations occurring during surgery.
