DoseCV: Dose coefficient calculation from MCNP simulations with MRCP phantoms.

Abstract

The level of detail of computer phantoms has increased over the years, thereby reproducing the human body more reliably. The Mesh-type Reference Computational Phantoms are an evolution of those from ICRP Publication 110, and are now available in polygon meshes. Analyzing MCNP simulation results using these phantoms can be time consuming and error prone due to the large amount of data generated by the program. This article then proposes the creation of a software called DoseCV to help process the output data from the MCNP simulations. The POLY2TET tool was used to tetrahedralize the phantoms, and DoseCV was used to process the output data. The results obtained were validated by comparing them with ICRP Publication 116 data. In general, considering the DCs found for the six simulated energies, an error of less than 5% was obtained for 88.9% of the target tissues of MRCP-AF and 76.7% of MRCP-AM. In its actual version, DoseCV can convert tally data into a dose coefficient (DC), equivalent dose conversion coefficient (CC[H_T]), effective dose conversion coefficient (CC[E]), equivalent dose (H_T), and effective dose (E). The combined use of POLY2TET and DoseCV proved to be an effective tool for processing data from the MCNP simulations.
