CT to MCNP

A script used to convert CT(nii) files to MCNP input files. Your must supply a tmol file which must contain mode card and material card. examole.toml is a template file.

Requirements

numpy, SimpleITK, toml

How to use

python main.py -c path/to/your/toml/file -d directory/to/save/inp

Toml Template

1. ct
   path to your CT(nii) file(s).
2. Mode
   It is used for MCNP mode card. It is a string array.
3. Material
   It is used to convert CT images to voxels. You should type [material.id] for each material. id is the group and is used to generate Mn in MCNP. In each group, hu_interval indicates the CT value interval. density is the tissue density in this interval. nucleon and fraction is components and regarded fractions of this material. nucleon is a series of integers: Z * 1000 + A. fraction is a series of floating-point numbers. Their meanings is same as MCNP.
4. Source(Optinal)
   It is used to generate SDEF card. Use keyword = [a series of values]. If you want to use SI and SP, please use a dict shows in example.toml.
5. Tally(Optinal)
   It is used to generate fmesh4 card. Only this tally card is supported by this script. particle indicates the type of particle recorded. And FM, DE, DF can also be added.
6. Output Control(Optinal)
   It is used to generate nps, prdmp and other card.
