Abstract :
Image-guided neurosurgery depends on both high image contrast and resolution. With pre-operative images, surgeons can precisely navigate using specialized instruments to in-vivo targets of interest such as the globus pallidus or subthalamic regions. Current MR imaging techniques, however, do not offer the full resolution and contrast-to-noise requirements needed by these surgical methods. This paper examines a technique based on projections onto convex sets (POCS) and relies on superresolution restoration that reaches high contrast and resolution for deep brain stimulator implantation surgery. An inversion process is introduced for combining multiple scans at different orientations with downsampled measurements producing a single data volume of high resolution and contrast
