Abstract:: Objective To design a set of X-ray machine power supply resistance measurement procedures for reducing the effects of the system errors of the measuring instruments and noise interference, and accurately measuring the power supply resistance of the X-ray machine. Methods Based on the signal injection method to measure resistance, LabVIEW software and the signal conditioning module produced by NI were used to design a program for measuring the internal resistance of power supply. The designed program could not only generate stable sinusoidal excitation current, but also measure response voltage, response current and phase difference, and then the power supply resistance of the X-ray machine was obtained. Results The system test showed that the measurement program could continuously measure the power supply resistance of the X-ray machine for a period of time, and that the average power supply resistance obtained was closer to the actual situation. Conclusion The proposed program can accurately measure the power supply resistance of the X-ray machine, providing a new method and idea for accurately measuring the power supply resistance of the X-ray machine.
