Brainlab CRANIAL/ENT OPTICAL - 3.4 Instrument Calibration Matrix

3.4 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
Before Using
Warning
Ensure that the reference array position does not change when using it for calibration and
verification as this leads to inaccurate tracking.
If you calibrate instruments using the calibration point, refer to the software user guide.

①
Reference Plane 1
Calibrate:
• Chisel tips
• Flat-tipped instruments
②
Reference Plane 4
Reference for:
• Tip distance of instruments calibrated in the V-inset
③
Reference Plane 2
Manually determine the width of tips and to calibrate:
• Chisel tips
• Flat-tipped instruments
④
Reference Plane 3 (V-inset)
Reference for:
• Shaft diameter of instruments calibrated in the V-inset
⑤
Receptacle (example)
Calibrate the long axis of:
• Short shafts
• Shafts that do not reach reference plane 4 (when the in-
strument is positioned in the V-inset)
