System zur Bestimmung der Position eines Punktes auf einem Gegenstand

摘要

A system and method are disclosed for determining a global position of an anatomical structure. The system utilizes a surgical navigation system and a substrate that is capable of being removably mounted to an outer surface of a user's body. The substrate includes a positional device and a sensor that is tracked by the surgical navigation system. A finger mounted structure capable of communicating with the positional device is also provided. The concatenation of a position of the sensor and a position of the finger mounted structure allows a global position of a point on the anatomical structure to be determined by a computer system.
