Imagine giving a surgeon an "X-Ray vision" ability, that is, allowing him to look at a patient and see through skin, bone, fat to visualize internal structures, like tumor or blood vessels, exactly as they occur within the patient. Imagine also allowing the surgeon to see structures that are not normally visible to the human eye, such as the position of functional cortex. Imagine allowing him to insert instruments through narrow openings in the body, yet still be able to visualize the full anatomical context around the instrument. Such capabilities would enable a surgeon to better plan procedures, to navigate through delicate procedures and to evaluate the effectiveness of surgical procedures, e.g. "have I removed all of the tumor". This talk will describe such image guided surgical systems, currently in regular use at Brigham and Women's Hospital in Boston for neurosurgical and other cases. The system combines a suite of computer vision techniques, and allows a surgeon to visualize internal structures in registration with the patient, to interactively probe points within the patient and see the full anatomical context of his position, and to evaluate progress of the surgical procedure. Related techniques allow a clinician to noninvasively map functional areas of the cortex, such as motor cortex, in order to provide the surgeon with registered information about critical structures during surgery.
