摘要：
A calibration device is provided having a body with an exterior surface configured for placement about a tool such that the body rotates about a tool axis. One or more fiducial marker is positioned on the exterior surface and in communication with a tracking system. A fixed fiducial marker array is provided that is also in communication with the tracking system. A calibration tool defines the tool axis relative to the fiducial marker array. A surgical system is also provided with a tracking module that calculates a center point of the rotation or a normal vector to the circular path to define a tool axis orientation. A method of using the surgical system and defining a tool axis relative to a fiducial marker array is provided. A system for defining a robot link orientation or tracking a tool a medical procedure and a fiducial marker array are provided.
