Scope
YY/T 1542-2017 is the English-translated version of 数字化医用X射线设备自动曝光控制评价方法.
YY/T 1542-2017 is the Chinese pharmaceutical industry standard that gives the method for evaluating the automatic exposure control of digital medical X-ray equipment, the circuit that ends the exposure when the detector has received enough radiation.
It sets out the phantoms and the beam qualities, the measurements of the resulting detector dose and image, and the criteria by which the consistency of the control across thicknesses, tube voltages and fields is judged.
Equipment with other kinds of automatic control may use it as a reference. Issued on 2 May 2017, it has applied since 1 April 2018.

terms and definitions apply to this document.
3.1 Automatic control system
In an X-ray apparatus, the power supplied to the X-ray tube assembly is measured by one or several doses of radiation or corresponding physical quantities Control or limit the system.
3.2 Automatic Exposure Control automaticexposurecontrol; AEC
In X-ray equipment, one or more loading factors are automatically controlled to obtain the desired mode of radiation at the preselected location formula. Automatic exposure control is also known as automatic exposure control.
3.3 Automatic exposure rate control
In X-ray devices, the radiation dose rate is automatically controlled by the control of one or more loading factors so that, at the preselected location and The mode of operation to obtain the desired amount of radiation for a predetermined loading time.
3.4 Automatic intensity control
In X-ray equipment, one or more loading factors are automatically controlled in order to obtain the desired radiation dose rate at a pre-selected location mode.
