Scope

This document specifies the method for checking the constancy of the X-ray system,
mainly to check the constancy of the X-ray tube voltage and tube current, AND to check
and evaluate the X-ray tube voltage and tube current changes, that may be caused by
the aging of the X-ray tube anode target.
The method, which is specified in this document, is to measure the dose rate, after
defining a filter plate of certain thickness, based on the determined X-ray tube, the filter
plate and the measuring device and the distance.
The method, which is specified in this document, is very sensitive to tube voltage
changes, BUT it cannot measure the absolute value of the X-ray tube voltage. Therefore,
a reference value needs to be given and confirmed, for example in an acceptance test of
an X-ray system.
This document is intended for periodic constancy checks of X-ray systems, by testers
using the thick plate filter method, which is a relatively convenient technique.
This document applies to the constancy check of the X-ray system, after replacement
of components, that may affect the voltage of the X-ray tube.
This document applies to all types of X-ray systems, such as potentiostatic, half-wave
rectified and pulsed, high-voltage generators, which have a tube current greater than 1
mA.
