We have proposed a method to obtain the electron density and effective atomic number from the attenuation coefficients of multi-energy X-rays. The simulations were performed using NIST’s database and demonstrate that our approach can facilitate electron density measurements within accuracy of 1% in a human body. The proposed method exhibited an improvement in the accuracy of electron density measurements, which were obtained from experimental linear attenuation coefficients using a conventional laboratory X-ray source with energy spectrum.
