英文摘要：

In order to ensure the accuracy of the non-invasive current meter for the X-ray diagnostic x-ray machine in our country and regions, non-invasive current meter measurement and calibration are analyzed according to domestic calibration of current meters and diagnostic radiation verification procedures. Combined with physical environmental conditions of non-invasive current measured, technical requirements for the non-invasive current meter and its standard equipment are proposed. Detailed testing theory and data processing methods are described to carry out calibration. The radiation source was firstly introduced to the current instrument calibration work as a trigger signal. Using standard current source, many non-invasive current measurement instruments are researched and analyzed by experiment to prove the calibration work for science, operability and effectiveness.
