Constancy Test

Together with other characteristic values, the daily test values
are checked for constancy monthly. These tests are performed
on the complete set of phantoms.
In addition, the CTDI (CT Dose Index) must be measured at least
once every six months. The CTDI must also be measured after
any maintenance work that might have altered the test results.
We recommend having the constancy test and the CTDI meas-

If you want to conduct the constancy test and the CTDI meas-
urement yourself, you must perform all steps of the constancy
test or the CTDI measurement under your own responsibility.
