Quick Reference - QA Calibration
Daily Calibrations should be performed prior to patient scanning to ensure quality bone density estimates. If a
successful calibration has not been completed within the last 14 days, scanning will be disabled.
Check the Calibration Standard for bent corners, damaged plastic, or loose parts (when shaken). If dam-
aged, contact Norland Customer Service.
Click on Calibration > Begin QA in the DXA Database Navigator window. Click on
in the Cal-
ibration tab window. The system will prompt the operator to place the calibration standard on the scanner and
mark point A.
Place the standard on the patient surface in the proper orientation as shown. Align it with the corresponding
marks on the table surface.
Switch ON the positioning laser.
Caution:
Do not stare into the beam.
Use the arrow buttons to move the scanner arm so the laser positioning dot is on the ‘+’ point on the Cal-
ibration Standard Plexiglas surface identified by the inscribed letter “A” and press the MARK button.
Use the arrow buttons to move the scanner arm so the laser positioning dot is on the ‘+’ point on the Cal-
ibration Standard Plexiglas surface identified by the inscribed letter “B” and press the MARK button.
Place the QC Phantom in the marked location next to the Calibration Standard, parallel with the backrest.
The 'C' should be to oriented to the right side of the table, (operator facing the table).
Move the scanner arm so that the laser positioning dot is on the dot (or X) by point “C”.
First MARK the dot at point “C”, then MARK the dot at point "D".
The scan of the Calibration Standard proceeds automatically to completion without operator intervention and
the estimated remaining time is updated periodically. Total time is about 25 minutes.
Verify that the PRECISION and ACCURACY fields in the window display the OK status on the BMD, Fat,
and Lean fields.
Click on
to print the results for storing in the calibration log.
Click on Stop and Cancel any time before the QA Results window appears to terminate the calibration pro-
cedure. The calibration files will revert to the previously recorded values.
Note:
Should any part of the calibration process fail, repeat the calibration once. If the diagnostic tests
fail the second time, shut the system down, re-start and perform calibration. If further difficulty is
encountered, contact your Norland Customer Service representative. Refer to the Operator’s Guide
for other troubleshooting options.
