Uniformity Calibration Sequence

The  uniformity  calibration  is  to  ensure  that  density  measurement  of  the  system  (Hounsfield
units) is calibrated correctly.

As per the previous calibration, go to the calibration page and click on Uniformity Calibration.
This time insert the clear Uniformity Calibration phantom by placing it on the CT pedestal.

The phantom has a location stud that will center the phantom on the pedestal.   Once positioned
click Okay.

Check the box to confirm the Phantom is placed and proceed by clicking Start.

As before the calibration will begin taking a full 360-degree image of the phantom which takes
up to four minutes.
