Abstract

A system is disclosed for calibrating the position of a medical instrument (10) in a system for monitoring the medical instrument (10) in a surgical environment. The system includes a position detection unit (14), data representative of at least two points having a fixed spatial relationship with respect to the position detection unit (14), and an instrument tip (20) that may be positioned at a particular tip (20) location point to permit the system to define the plane described by the two points and said tip (20) location point.
