Brainlab CRANIAL/ENT OPTICAL TRACKING - Instrument Calibration Matrix

3.3 Instrument Calibration Matrix
Introduction
The Instrument Calibration Matrix (41874) is used to:
• Calibrate the axis, vector, diameter, and tips of non-precalibrated instruments
• Verify and validate calibration accuracy of precalibrated instruments
Calibration Point
If you calibrate instruments using the calibration point, refer to the software user guide.
