“…As stated in the literature, MCNPX is an extended version of MCNP that transports many particles over a boarder range of energy than MCNP4C. On the other hand, MCNP4C is capable of transporting photons, neutrons, and electrons in different energy range, and the differences between these two versions (MCNPX and MCNP4C) are not related to the parameters that affects photon/electron transport in diagnostic energy range (Kirk 2010;Mourtada et al 2003). Therefore, given our access to MCNP4C, this code was used as the Monte Carlo transportation code.…”

In head computed tomography, radiation upon the eye lens (as an organ with high radiosensitivity) may cause lenticular opacity and cataracts. Therefore, quantitative dose assessment due to exposure of the eye lens and surrounding tissue is a matter of concern. For this purpose, an accurate eye model with realistic geometry and shape, in which different eye substructures are considered, is needed. To calculate the absorbed radiation dose of visual organs during head computed tomography scans, in this study, an existing sophisticated eye model was inserted at the related location in the head of the reference adult male phantom recommended by the International Commission on Radiological Protection (ICRP). Then absorbed doses and distributions of energy deposition in different parts of this eye model were calculated and compared with those based on a previous simple eye model. All calculations were done using the Monte Carlo code MCNP4C for tube voltages of 80, 100, 120 and 140 kVp. In spite of the similarity of total dose to the eye lens for both eye models, the dose delivered to the sensitive zone, which plays an important role in the induction of cataracts, was on average 3% higher for the sophisticated model as compared to the simple model. By increasing the tube voltage, differences between the total dose to the eye lens between the two phantoms decrease to 1%. Due to this level of agreement, use of the sophisticated eye model for patient dosimetry is not necessary. However, it still helps for an estimation of doses received by different eye substructures separately.

“…The Radiation Safety Information Computational Center (RSICC) is one of the world's leading resources for a broad range of the best available nuclear computational tools and services [24]. For an overview of Monte Carlo codes managed by RSICC, see the paper [25]; Mercury has a similar set of features but is not currently released under RSICC. MCNP (Monte Carlo N-Particle) [26] is the most well known related Monte Carlo particle transport code.…”

“…Neste trabalho foi utilizado o MCNP5 (X-5 Monte Carlo Team, 2005) nas simulações. Este código foi desenvolvido pelo Los Alamos National Laboratory (LANL), e pode ser usado para o transporte de nêutrons, fótons, elétrons individualmente ou de modo acoplado (Kirk, 2010). Quanto à geometria, esse código possui uma vasta flexibilidade de modelagem geométrica, sendo possível a criação de geometrias a partir de superfícies e/ou por estruturas repetidas.…”
