Claim 0:
1. A multi-part medical marker comprising:
a spherical marker core comprising two corresponding parts fitted together to form the spherical marker core; and
a detectable surface formed from a retro-reflective laminar material applied to outer surfaces of the two corresponding parts of the spherical marker core and onto rims of the at least two corresponding parts,
wherein the rims of the two corresponding parts and rim areas of the retro-reflective laminar material applied to the outer surfaces of the two corresponding parts of the spherical marker core are cut off,
wherein cutting edges obtained by cutting off the rims of the two corresponding parts and the rim areas of the retro-reflective laminar material applied to the outer surfaces of the two corresponding parts serve as abutting edges where corresponding parts of the retro-reflective laminar material applied to the outer surfaces of the two corresponding parts abut each other,
wherein a first corresponding part of the two corresponding parts defines an extension disposed at a hollow side of the first corresponding part opposite from the outer surface of the first corresponding part,
wherein the extension defines a handling engagement section disposed at the hollow side of the first corresponding part,
wherein the extension defines a recess extending within the extension from the outer surface of the first corresponding 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.
