Abstract

A tracking reference fixation support configured to fasten a medical tracking reference to a patient's head, the fixation support comprising an elastically deformable base-plate having a bottom surface, the base-plate being configured to rest via the bottom surface against the surface of a patient's head; an interface-plate providing an interface for rigidly attaching a medical tracking reference to the fixation support; and at least one joint that couples the interface-plate to the base-plate, which allows the base-plate to deform while the interface-plate remains substantially dimensionally stable. The invention further relates to a corresponding tracking reference headband and to a corresponding method of providing a patient's head with a tracking reference.
