Abstract:
We describe an image-guided neurosurgery system which we have
successfully used on 70 cases in the operating room. The
system is designed to achieve high positional accuracy with a simple
and efficient interface that interferes little with the operating
room's usual procedures, but is general enough to use on a wide range
of cases. It uses data from a laser scanner or a trackable probe to
register segmented MR imagery to the patient's position in the
operating room, and an optical tracking system to track head motion
and localize medical instruments. Output visualizations for the
surgeon consist of an ``enhanced reality display,'' showing location
of hidden internal structures, and an instrument tracking display,
showing the location of instruments in the context of the MR imagery.
Initial assessment of the system in the operating room indicates a
high degree of robustness and accuracy.
