Abstract
A rigid frame that is positioned around the skull to define a multi-dimensional coordinate system. Multiple arms are coupled together with a support ring to increase the overall stiffness of the frame. The arms and the support ring are made from a plastic material that makes the frame appear transparent in CT and MRI images. Receptors provide a mounting base upon which the frame is repeatedly attached and detached from the skull at the same reproducible reference location. Each receptor is mounted to the skull with a screw that inserts through a rear end. A drill assembly and attachment assembly are used to secure the receptors in the skull.
