GB/T 41105.1-2021 English PDF (GBT41105.1-2021)

This document specifies a method, for directly and absolutely measuring the average high voltage, at the secondary side of the high-voltage generator of the X-ray system, at a constant potential (DC). It establishes the corresponding relationship, between checking the high-voltage output and the indicated value of the tube voltage, on the control unit of the X-ray system. This document is applicable to ensure the repeatable operation of X-ray systems. Tube voltage affects the penetration properties of materials AND the contrast of X-ray images. It also affects radiation protection related requirements.
