Monte Carlo simulations studies in small animal PET using GATE

This work is focused on the use of a simulation system dedicated for small animal PET imaging, in order to produce realistic simulated mouse exams. Sets of gold standard images where physical effects not taken into account are presented. A preliminary approach of the physiological process of the respiratory motion and the implementation of a lung tumor is shown in this paper. The quantitative and qualitative simulated data results show a good agreement with the real values.
