ارزیابی باریکه‌های الکترونی MeV6 و MeV8 حاصل از شتابدهنده خطی نپتون 10PC با استفاده از روش مونت کارلو [PDF]

مجله علوم و فنون هسته‌ای, 2007
باریکه‌های الکترونی بطور وسیعی در پرتو درمانی مورد استفاده قرار می‌گیرند. با توجه به اینکه مقدار انرژی اسمی الکترونها ویژگیهای باریکه‌های الکترونی را برای مقاصد درمانی به اندازه کافی فراهم نمی‌آورند، لازم است داده‌های دْز عمقی را برای باریکه‌های الکترونی

Validation of Monte Carlo simulation of 6 MV photon beam delivered by the Vero4DRT linear accelerator using BEAMnrc and DOSXYZnrc

, 2020
The goal of this project is to develop a Monte Carlo (MC) simulation model for the 6MV Vero4DRT platform which is a stereotactic ablative radiation therapy (SABR) medical linear accelerator. This MC model can simulate a variety of radiotherapy delivery techniques, including three-dimensional conformal radiotherapy (3DCRT), dynamic conformal arc (DCA ...

Assesment of Percentage Depth Dose, Beam Flatness, and Beam Symmetry in Different Media of Different Photon Energy Beams using DOSXYZnrc Monte Carlo Code

Nigerian Journal of Pure and Applied Sciences
In radiotherapy treatment planning, accurate dose calculation is important. Any difference in photon energy might affect dose deposition. The DOSXYZnrc Monte Carlo code was utilized to simulate photon interactions in heterogeneous media in order to evaluate dose distributions in water, lung, soft tissue, and bone.
