<title>Multimodality interactive stereoscopic image-guided neurosurgery</title>

Abstract

We demonstrate the use of integrated multi-modality data (MRI, MRA, DSA, PET and live video) and 3D stereoscopic imaging in the context of image-guided neurosurgery. We consider here the integration of anatomical data (MRI), vascular data (DSA and MRA) and functional data (PET) derived from the patient undergoing the surgical procedure. In addition live video images are merged with renderings of the data stored in the computer. The integration of multimodality data provides the surgeon with interactive and intuitive access to a comprehensive overview of the brain structures on which surgery is being performed. Ready access to this information enhances the surgeon's ability to avoid critical vessels and structures of functional significance.
