The workstation provides a multitude of data – including magnetic resonance imaging (MRI), a three-dimensional image of the surgical field, sonic information, and quantifiable haptic (or tactile) feedback from tool-tissue interaction – that enable the surgeon to experience the surgery through sight, sound, and touch. Because the human brain makes decisions based on sensory input – and, of course, experience – such data are essential for the surgeon to make the most informed choices possible during surgery.
