Claim 0:
1. A tracking reference fixation support configured to fasten a medical tracking reference to a head of a patient, the fixation support comprising:
an elastically deformable base-plate having a bottom surface, wherein the base-plate is configured to rest via the bottom surface against a surface of the head of the patient;
a stiff interface-plate which provides an interface at a location spaced from the base-plate in a direction substantially perpendicular to the bottom surface, the interface being configured to rigidly connect to the medical tracking reference, wherein the stiff interface-plate is formed as a single element that connects between the interface and the elastically deformable base-plate, wherein the stiff interface-plate and the elastically deformable base-plate connect to each other at a first hinge section having a first bending axis and a second hinge having a second bending axis extending parallel to the first bending axis, thereby allowing the base-plate to flex below the interface plate and about an axis extending parallel to the first bending axis and the second bending axis while the interface-plate remains substantially dimensionally stable, and
a fastening member which is adapted to engage a pair of fastening sections disposed on opposite sides of the base-plate, the fastening member being further adapted to reach around the head of the patient so as to fasten the fixation support to the head of the patient by being tightened.
