ABSTRACT
Objective:Mobile X-ray radiographic Units to appear in the clinical application of high voltage circuit judge special case of failure, the analysis in order to provide effective and reliable service basis. Methods: Preliminary judgment based fault location fault code, using stepwise exclusion analyze, judge, and determine the cause of the failure lies. Results:The high-voltage inverter element models of mobile DR, the driver circuit, the output voltage discharge waveform judgment and other issues have a better understanding, to facilitate the exclusion of equipment failure. Conclusion:Special case of X-ray radiographic Units failure high voltage circuit analysis and troubleshooting, especially for the inverter circuit analysis, X-ray radiographic appear to take timely and appropriate repair method when high pressure overload.
