Computer-aided neurosurgery. View of a technician preparing a patient for brain surgery by mapping his head. A 3-dimensional model of his brain is seen on the monitor at upper right, with the area to be operated on highlighted green. Here, a laser (red) scans the patient's head. LEDs (light-emitting diodes) are taped to his head to aid positioning. An image of the patient's brain is then superimposed on a live image of the patient's head during surgery. This facilitates the surgery, and reduces the risk of damaging healthy brain tissue during the excision of a tumour, for instance. This system was developed by Eric Grimson at MIT, USA.
