Personnel

Director: Terry Peters PhD FCCPM

Consultant/Research Associate: Bruce Davey, PhD (ISG Technologies)

Research Assistant: Rob Flanz

Graduate Students:

MR Image acquisition for surgical guidance:
The acquisition of high resolution images with rigorous geometrical accuracy.
Image-guided Neurosurgery (IGNS):
Techniques for real-time guidance of the surgeon in the operating room based on 3-D images of the brain reconstructed from multiple modalities.
Stereoscopic Visualization:
Development and evaluation of effective means of displaying 3-D images stereoscopically to the surgeon.
Multi-modality imaging for IGNS:
The effective integration, in a stereoscopic environment, of 3-D images from multiple modalities, including means of objectively comparing images of the same phenomenon (e.g. angio) from various modalities.
Integration of stereoscopic video with IGNS:
Integration of the real world (surgical instruments; what the surgeon actually sees) with the model world (computer reconstructed 3-D images of the brain)
Ultrasound Guidance for Neurosurgery:
The use of intra-operative 3-D ultrasound, correlated with the 3-D MRI models, to track the movement of tissues within the brain during surgery.
Accuracy issues in IGNS:
An assessment of the sources of error in IGNS, and the development of techniques, including fiducial frames, to minimize such errors.
Integration of EEG maps with IGNS:
Treating the surface voltages sampled by EEG as an imaging modality and integrating the resulting dynamic voltage maps with the 3-D intra-operative MR images.
