Abstract

In diagnostic radiology, the determination of bremsstrahlung spectrum is essential for patient absorbed dose estimation and image quality improvement. In this paper, we surveyed the X-ray emission spectra of different peak voltages 50, 70, 85, 125 and 150 kV by using MCNP5 code. Besides, the effects of filter, collimator and anode material on X-ray spectra have also been investigated. The simulation results fairly agree with experimental spectra obtained by P.T. Talla et al. (2009)
