1. A medical laser target marker device, comprising:
- a marker body having a surface on which are arranged;
a retro-reflector for receiving and reflecting light;
at least one first medical tracking marker having a first functional configuration; and
at least one second medical tracking marker having a second functional configuration different from the first functional configuration;
wherein the retro-reflector, the first functional configuration and the second functional configuration correlate to three different tracking technologies, respectively.

16. A method of verifying a calibration of a medical tracking system using a medical laser target marker device including i) a retro-reflector for receiving and reflecting light, and ii) at least one first medical tracking marker arranged on the laser target marker, said at least one first medical tracking marker having a first functional configuration, the method comprising:
-
using the retro-reflector to determine a spatial location of the medical laser target marker device; using the at least one first medical tracking marker to determine a spatial location of the medical laser target marker device; and if the spatial location as determined from the retro-reflector and the spatial location as determined from the at least one medical tracking marker are within a predetermined threshold, concluding that the medical tracking system calibration is within a calibration tolerance. - View Dependent Claims (17, 18)
