8 - 8 Checking dose settings
Adjust the H and D Settings 8
To adjust the
H value, go to Modify low dose scaling (80, 70, 45) and
D value, go to Modify high dose scaling (100, 80, 60) and
enter the new values, separated by a comma, e.g. 100,80,60. The values represent the
factor in % for (Mo/Mo, Mo/Rh, W/Rh).
Three settings try (short-term, is valid for one measurement only), save (long-term, valid
also after reboot) and load (effective, valid until the system is rebooted) can be used in
the drop-down menu above the values.
To change the values permanently, enter the correct values and select save, then use
load to load them before you start another exposure.
Calculation of the new Mo/Mo dose scaling value:
NewScalingValue = OldScalingValue * DoseValue
Nominal
/ DoseValue
Measured
DoseValue
Nominal
for H = 130 µGy
DoseValue
Nominal
for D = 190 µGy
Calculation of the new Mo/Rh, W/Rh dose scaling values:
NewScalingValue = OldScalingValue * PixelValue
Mo/Mo
/ PixelValue
Measured
Proceed as follows:
1. Go into the service software and select Utilities -> Escape to OS and enter the
following command in the Command field.
start explorer http://brick
2. Select Brick -> AEC Configuration.
3. The BRICK software switches to a higher user level, thus a Username and
