The double-scattering system including  the range modulation wheel in a proton treatment  nozzle was designed by using the NEU code. The Monte  Carlo particle-transport code MCNPX was used in  predicting dose distributions in this book. In the  passive-scattering treatment technique, a rotating  range modulation wheel is used to generate a spread- out Bragg peak depth-dose distribution. This dynamic  geometry cannot be modeled in the simulation of  MCNPX. This book provided an application of  the ¿replacing dynamic by static¿ method to solve  this problem. A script ¿mcnp_pstudy,¿ written in  Perl programming language, was used to set up a  series of MCNPX input files, each of which contains  the parameters of a specified step of the wheel, and  invoke MCNPX to simulate each problem successively.  The other Perl script ¿merge_mctal¿ was used to  merge all the separate simulation results into one  file containing the simulation results that are  equivalent to a ¿dynamic¿ simulation.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844317343\"\u003e\u003ch3\u003eMonte Carlo Simulation for Proton Therapy\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844317343","offer_id":39495979237469,"sku":"9783844317343","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/83b2052b-5243-455a-83af-1320f49d9c9e.jpg?v=1758947907","url":"https:\/\/shop.autorenwelt.de\/products\/design-and-simulation-of-a-passive-scattering-nozzle-in-proton-therapy-von-fada-guan","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
