CT2MCNP: An Integrated Package for Constructing Patient-Specific Voxel-Based Phantoms Dedicated for MCNP(X) Monte Carlo Code

We introduce a fast and well-structured package for constructing voxel-based computational phantoms as MCNP(X) input file based on CT DICOM images. Our program which has been implemented under a graphic user inter-face provides several basic image processing tools for manipulating images. The MCNP materials are interpreted from the CT numbers of DICOM images. Two modes of phantom creation have been provided using individual cells and lattice. In the former, the program uses a fast merging algorithm for reducing the number of cells and in the latter, an optimized approach has been followed. This software has strong potential in applications in radiologic, dosimetry and therapeutic MCNP- based Monte Carlo studies.
