Abstract:: Abstract: Objective To solve the problems of high cost, radiation and circuit packaging of X-ray machine in the experimental teaching of medical imaging and medical imaging technology. Methods Based on the basic circuit of X-ray machine, the circuit structure was optimized, and the circuit design of intuitive function module was adopted. The direct currents of tube voltage measurement circuit and tube current measurement circuit were provided by power transformer. Moreover, 89C2051 single chip was used for realizing exposure time setting, exposure time control, display circuit control drive and other functions. Results The proposed device which did not produce high voltage and X-ray could be used to simulate the working principle and main circuit structure of medical X-ray machine, and used in the experimental teaching of X-ray machine, so that students can not only learn and master the working principle and circuit structure of X-ray machine, but also measure the main working characteristics and parameters of X-ray machine, and observe and measure circuit waveforms. Conclusion The proposed device can solve the shortages of experimental teaching equipments, and can be widely used in the experimental teaching of medical imaging, medical imaging technology and other related majors in medical colleges.
