Applications of SEDECAL mobile X-ray radiographic units / 中国医学装备

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.

Development of portable HF X-ray machine / 医疗卫生装备

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.
