DLC-0256 ZZ-VIP-MAN.

1. NAME OR DESIGNATION OF PROGRAM:  ZZ-VIP-MAN

3. DESCRIPTION OF PROGRAM OR FUNCTION

Risk to the human body due to radiation exposure can be assessed by ICRP conversion factors, which rely on the accuracy of virtual human phantoms to portray the most precise results. VIP-Man phantom allows for the ability to investigate subtle dose variations in relatively small structures from various charged particles.

4. METHODS

ZZ-VIP-Man (vp-n.inp) is a voxel phantom (also called tomographic phantom) that represents the entire body of a human.  The phantom was developed from segmented cadaver images originally obtained in the Visible Human Project. The phantom was implemented in MCNP/MCNPX codes at a 4mm x 4mm x 4mm voxel size.  The input deck allows for the use of MCNP/MCNPX codes to model the transport of photons, electrons, and neutrons through an anatomically realistic adult male for radiation protection, imaging and therapy applications.  The phantom geometry can also be extracted from the input file for other purposes such as visualization.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

A user should not modify or redistribute the VIP-Man phantom without the knowledge of the original developer, Professor X. George Xu, at Rensselaer Polytechnic Institute. Publications associated with this phantom should bear an appropriate reference to the paper (Xu, et al, 2000) and acknowledgement of this tool shared through RSICC.

6. TYPICAL RUNNING TIME

About one hour for one million particles depending on the computer hardware.

8. RELATED OR AUXILIARY PROGRAMS

MCNP5/MCNP6/MCNPX executables are required (not distributed with the package).
