DoseCV: Dose coefficient calculation from MCNP simulations with MRCP phantoms

Area of Science:

• Medical Physics
• Computational Dosimetry
• Radiation Protection

Background:

• Advanced computer phantoms, like Mesh-type Reference Computational Phantoms (MRCPs), enhance human body representation.
• Analyzing MCNP simulation data with detailed phantoms is data-intensive and prone to errors.

Purpose of the Study:

• To develop and validate DoseCV software for efficient processing of MCNP simulation output.
• To streamline the conversion of MCNP tally data into various dose metrics.

Main Methods:

• Utilized POLY2TET to tetrahedralize MRCPs.
• Employed DoseCV software to process MCNP simulation output data.
• Validated results against ICRP Publication 116 data.

Main Results:

• DoseCV successfully converted MCNP data into dose coefficients (DC), conversion coefficients (CC[HT], CC[E]), and doses (HT, E).
• Validation showed less than 5% error for 88.9% of MRCP-AF tissues and 76.7% of MRCP-AM tissues.
• The combined use of POLY2TET and DoseCV proved effective for MCNP data analysis.

Conclusions:

• DoseCV is an effective tool for processing MCNP simulation data with detailed computational phantoms.
• The software enhances accuracy and efficiency in radiation dose assessment.
• This approach aids in reliable dosimetry for radiation protection applications.
