CHAPTER 4:  Calibration and Quality Assurance (QA) Procedures

 

Calibration Procedures: 

There are seven Calibration/Alignment Procedures.  These steps should all be 
performed in sequence at installation of the system and then again on an annual 
maintenance schedule. Calibration Procedures should be performed only by factory 
trained technicians.  
 
To complete all of the calibrations, allow at least 2 hours.  
 
The Calibrations to be performed are: 
 
 
 
 
 
 
 
 

 

 

 

The tools required for Calibration: 
 

Centering Tool      

 

Geometric Phantom with alignment set screw 

 
Ensure that all safety precautions are taken for the location in which these procedures 
are being performed.  If the office is equipped with the Door Interlock Option, ensure that 
the appropriate measures are taken to be able to perform a scan and fire the x-ray.  If 
needed, there is always the option to release the Scan button or to use the E-Stop to 
stop the x-ray in the middle of a calibration.  If the E-Stop is depressed, it will cause the 
power switch on the back of the scanner to shut off.  Reset the E-Stop by rotating it, then 
restart the scanner by flipping on the power switch at the back of the scanner.  Then 
restart the calibration at the beginning of the calibration that was interrupted.  If the scan 
button is released prematurely during a calibration, rerun the current calibration. 
 
Log-in required for Calibration:  
Start on the Acquisition Station terminal.  Close any open applications.  For the 
Calibration Procedures, the “cbadmin” account must be logged in.  To determine the 

current user that is logged in, left mouse click on the Windows Start icon 

 in the 

lower left corner of the screen.  If the user is anything other than “cbadmin”, in the upper 
right corner, then the user will need to be changed.   

1.  Find Center of Rotation 
2. A/B/Center Distance Measurement 
3. Collimator Setup 
4. Panel Rotation 
5.  Panel Gain Calibration  
6.  Panel Air Normalization Calibration 
7. Geometric Calibration
