Geometry Calibration
The Panel Calibration must be performed prior to running the
Geometry Calibration. It is recommended to run the Geometry
Calibration once a year or if image quality becomes degraded. The
Geometry Calibration also runs in both Portrait and Landscape
positions and takes about 12 to 15 minutes to complete.
11. Perform the Panel Calibration (procedure listed above).
12. Mount the Phantom Platform (shown below).
13. Ensure that the BB Phantom is level.
14. Center the BB Phantom on the platform using the alignment
holes on the platform and bottom of phantom.
15. Align the BB Phantom crosshair slits with the laser cross beams.
For an accurate alignment, the laser beams should penetrate
though the phantom crosshairs and appear on the receptor panel.
16. From the Calibration menu (already displayed from the Panel
Calibration) click the Preview button.
17. The settings screen is displayed, click OK .
