5 Preliminary procedures
5.4 Beam limiter test
This functionality has the purpose of allowing the user to check proper collimation.
The collimator's positions are pre-set by the manufacturer and may not be changed by the user.
1. From the main toolbar select Tools

Scanner Test .
2. From the window bar select Tools  Beam Limiter Test. Select the desired FOV.
3. Set the radiological parameters depending on the selected FOV (S tandard : SFS, 1 mA, 10 msec, KV
= 110; HiRes standard : SFS, 6 mA, 10 msec, KV = 110)
4. Perform an acquisition.
5. Verify the acquired image is correctly collimated (the green rectangle should be entirely included in
the gray acquired area. The edges of the rectangle must be included between the two couples of red
lines).
WARNING:
If the grey image acquired is not correctly collimated
within the red lines, please contact our Technical
Support.
