Checking dose settings 8
Enable/Disable Dose Calculation 8
If desired, the Dose Calculation System can be enabled/disabled. As a default the Dose
Calculation System is enabled.
This is done by starting the Dose Calculation Program in the service PC.
From the Mainmenu in the Service program choose:
Configuration Dose Calculation Enable/Disable Dose Calculation.
To show the calculated dose values on the control console, enable this option (ON).
The dose will be shown in the mAs/mGy display (Fig. 1), the value shown will shift from
mAs to dose with approximately 2 second intervals.
Configuring of Dose Calculation System 8
The Dose Calculation System comes with factory default values. Normally, the factory
default values should be used. If desired, measurements of HVL (Half Value Layer) and
Dose Exchange factors can be performed to improve the accuracy of displayed dose val-
ues. These measurements should be performed by the hospital’s medical physicist, and
are described in the document Radiographic Handbook, Dose Calculation System,
SPB7-230.206.01.... The measuring procedure is quite complicated and should only be
performed by a physicist familiar with similar measurements. If the HVL and Dose
Exchange values are to be measured, the document Software, SPB7-250.816.01...
describes how to enter the values in the Dose Calculation Program.
If reinstalling factory default parameters, all previously entered measured data (HVL val-
ues and Dose exchange factors) will be lost. However, the measured data should already
be noted in the document Radiographic Handbook.
Selecting "OFF" will only prevent dose values from
showing in the mAs/mGy display. Dose calculations
will still be performed, and can be printed out if the
printer option is installed.
