    Abstract: A method of calibrating an instrument for surgical intervention is provided. The instrument to be calibrated has a tip at a distal end thereof and a navigation array that is spaced from the distal end and is detectable in space. The navigation array has a fixed spatial and angular relationship with the tip. The method comprises the steps of: placing a calibrator on the tip of the instrument such that the tip is positioned within the calibrator at a known displacement from the centre of the calibrator, the calibrator having a circular shape and being detectable as a single point in space; detecting the position of the navigation array and the centre of the calibrator; and determining the position of the centre of the calibrator relative to the navigation array, thereby calibrating the position of the tip of the instrument relative to the navigation array. There is also provided a calibrator for use in such a method.
