Obtaining an X-Ray of the Zubal Phantom by Monte Carlo Simulation

Radiation transport in matter has attracted great interest since the beginning of the 20th century. High-energy photons, electrons, and positrons penetrate the matter undergoing multiple interactions where his energy is transferred to the atoms and molecules of the material, and secondary particles are produced. By multiple interactions a high energy particle produces a cascade of particles that is usually referred to as a shower. In each interaction, the energy of the particle is reduced and particles can be generated so that the evolution of the shower represents a degradation of the energy. The purpose of this work is to obtain x-ray images of the human body using the Zubal phantom. The transport of the radiation, crossing the phantom and arriving on the detector, is realized using the code MCNP (Monte-Carlo N-Particle transport). The images obtained are comparable to those obtained by a real radiological imaging system.
