Abstract :
In this work a parallelization technique for Monte Carlo calculation of the radiation absorbed dose is presented. The proposed method reduces the overall time of calculation exploiting the probabilistic nature of the problem. Reducing dose calculation times to meet practical application of use of results is a topic of great interest in the Monte Carlo simulation, dosimetry evaluation and treatment planning. The general problem of dose calculation parallelization was analyzed. The optimal number of calculation units for a given context was also determined.
