The method has been tested with a 16 16 16 cm3 phantom and distorted phantom edges with shifts up to 4 mm at the phantom corners were corrected by the distortion correction functions to within 0.2 mm. Test of the system with a stereotactic verification head phantom are underway to demonstrate that an intracranial target can be localized with submillimeter accuracy.
