حساب المدى و تغير الجرعة النترونية و الفوتونية في المعالجة بالبروتونات ضمن فانتوم مكافئ للنسيج الحي باستعمال حزم بروتونية متغيرة الطاقة و الكود MCNPX-2.3.0

Abstract EN

Proton facilities represent a major advance in radiation therapy in addition to scanning systems, because of excellent dose distributions around the tumor, and because of potentially lower whole-body dose compared with conventional radiotherapy methods such as photons.

In this paper Monte Carlo Code MCNPX- 2.3.0 was used, that has been verified to be a suitable tool to evaluate dose distributions in radiotherapy problems, to calculate the range, deposited energy and dose distributions in a phantom equivalent to organic tissue with protons energy between (50–130, 235 MeV).

In addition effect of the added thickness of Lexan material on change of protons’ range and dose distributions were studied.
