A metal or composite frame rigidly fixed to the skull with screws under local anesthesia, combined with an arc that allows Cartesian (x, y, z) coordinates to be calculated from CT or MRI images.
How it is used
Allows millimeter-precise localization of an intracranial target for brain biopsies, deep brain stimulation electrode implantation, stereoelectroencephalography electrodes or radiosurgery planning.
