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.
ABSTRACT
The portable high frequency (HF) X-ray machine for field use is introduced in this paper, which applies HF technology and the microcomputer. Compared with the traditional one, it has many new functions such as the self-motion exposal, real-time inspection and display, the alarm of the failure and the automatic disposal. With the advanced technology, it has overcome the deficiencies of the traditional one, including the overweight, bulkiness and unportability. Equipped with the portable mobile shelf, this machine is fit for field operations.
ABSTRACT
This paper presents a high voltage generator for the defibrillator.Its principle and design method are introduced.The high voltage generator is the core part of the defibrillator which is necessary toany hospital.There is nodomestic-patented defibrillator by now and published paper specialized in the principle and design method of the high voltage generator for the defibrillator.
ABSTRACT
