There is a need for frameless guidance systems to help surgeons plan t
he exact location for incisions, to define the margins of tumors, and
to precisely identify locations of neighboring critical structures. We
have developed an automatic technique for registering clinical data,
such as segmented magnetic resonance imaging (MRI) or computed tomogra
phy (CT) reconstructions, with any view of the patient on the operatin
g table. We demonstrate on the specific example of neurosurgery. The m
ethod enables a visual mix of live video of the patient and the segmen
ted three-dimensional (3-D) MRI or CT model. This: supports enhanced r
eality techniques for planning and guiding neurosurgical procedures an
d allows us to interactively view extracranial or intracranial structu
res nonintrusively. Extensions of the method include image guided biop
sies, focused therapeutic procedures, and clinical studies involving c
hange detection over time sequences of images.
