Robust Nonrigid Registration to Capture Brain Shift From Intraoperative MRI
The intraoperative magnetic resonance imaging system allows the neurosurgeon to acquire images of the brain during the neurosurgical procedure. In the case of brain tumor resection, this system helps to follow the deformation of the brain. However, even if it provides significantly more information than any other intraoperative imaging system, it is not clinically possible to acquire full diffusion tensor, functional MR or high resolution MR images in a reasonable time during the procedure. This transformation could then be used to update the set of pre-operative images to provide the surgeon with substantial information for the upcoming of the procedure.
