Claim 6:
7. A medical marker comprising:
a spherical marker core comprising semi-spherical parts mutually connected together at cutting edges of the semi-spherical parts to form the spherical marker core; and
a retro reflective laminar material on outer surfaces of the semi-spherical parts,
wherein rim areas of the retro reflective laminar material extend to the cutting edges of the mutually connected together semi-spherical parts,
wherein the cutting edges of the retro reflective laminar material are held in mutual abutting alignment,
wherein a first semi-spherical part of the semi-spherical parts defines an extension disposed at a hollow side of the first semi-spherical part opposite from the outer surface of the first semi-spherical part,
wherein the extension defines a handling engagement section disposed at the hollow side of the first semi-spherical part,
wherein the extension defines a recess extending within the extension from the outer surface of the first semi-spherical part towards a center of the spherical marker core,
wherein the recess defines an internal thread adapted to engage an associated connecting object thereby configuring the medical marker for selective attachment with an associated object to be tracked using the medical marker.
