A skull pin assembly for a head fixation device that allows for effective imaging with limited artifact is disclosed. The skull pin assembly comprises two components, a tip and a housing. The conical-shaped tip component engages the skull at a point and is configured to fit within the bore of the substantially cylindrical non-conductive housing component. The conical skull pin tip can be comprised of a material that causes limited artifact in medical imaging procedures. The conical skull pin tip can taper away from the point engaging the skull at a first angle and can seamlessly transition into a conical-shaped surface of the housing component. In one embodiment, a third surface of the housing component can also be tapered to meet the first surface of the tip component at the identical first angle of tapering.
