Output values of constancy testing (§16 Germany)
11
Determine the output values of the constancy testing at approx. 30 kV with the customer´s
own constancy test body (NORMI 7 test body etc.) and enter them in the form stapled to
the acceptance test certificate. Both tables must be checked
Procedure:
1.
On the control panel, select a value of approx. 30 kV and AEC.
2.
Place the test body on the object table flush with the chest wall side.
3.
Slide film cassette into the object table.
4.
Trigger the exposure and develop the film.
5.
Measure the resolution (A-D), density (1-4) and the over-radiation on the chest
wall side and enter in the form (steel balls).
6.
Read off the pen dosimeter and record the dose value.
