Modeling Methods for Medical Simulation Calculation with the Code MCNP

MCNP is a general-purpose Monte Carlo N-particle code that can be used for neutron, photon, electron, or coupled neutron/photon/electron transport. It’s used widely, but it is very complicated to construct its simulation model, especially when it is used in medicine field. MCNP often cannot run because the calculation model goes beyond the limit of MCNP geometry disposal capacity. Three modeling models with their own specialty will be put forward in the paper. According to these methods, the author programmed to realize MCNP automatic modeling and automatic conversion into MCNP input files. The program has been put into practice, and the result is satisfied.
