Purpose: This research aimed to estimate the Mass Attenuation Coefficient (MAC) for the various nanoparticles in diagnostic imaging in order to assess and compare the changes in a bulk state. Materials and Methods: To Using Monte Carlo N-Particle eXtended (MCNPX) code. nanoparticles were simulated in the target in order to compute the MAC considering the target.
