Investigating the effect of voltage fluctuations on the beam quality of X-rays in the range energy of diagnostic radiology

The purpose of this study was to investigate the effect of voltage ripple produced by X-ray machines on the quality of X-ray rays. For this purpose, the energy spectrum from the X-ray tube manufacturer should be simulated in the range of diagnostic radiography and verified by experimental results. The statistical analysis of the results showed that there is no significant difference between simulation results and experimental results. Then the effect of the ripple factor on the energy spectrum was simulated and investigated. In order to investigate the effect of ripple factor on the beam quality, the half-value layer HVL was calculated. The results of this study showed that the voltage fluctuations can reduce up to 56% of the HVL value at 100 kV and about 75% at 80kV voltage.
