OBJECTIVE We tested the application accuracy of an electromagnetic field-based image guidance system to compare it to traditional optically tracked systems. METHODS A plastic skull phantom was fitted with fiducial markers rigidly attached via self-drilling bone screws. Volumetric CT scan was obtained to simulate the clinical condition. A metal disc marked(More)
UNLABELLED OBJECT.: Brain shift during minimally invasive, bur hole-based procedures such as deep brain stimulation (DBS) electrode implantation and stereotactic brain biopsy is not well characterized or understood. We examine shift in various regions of the brain during a novel paradigm of DBS electrode implantation using interventional imaging throughout(More)
