TOPAS Simulation of the Mevion S250 compact proton therapy unit
As proton therapy becomes increasingly popular, so does the need for Monte Carlo simulation studies involving accurate beam line modeling of proton treatment units. In this study, the 24 beam configurations of the Mevion S250 proton therapy system installed recently at our institution were modeled using the TOolkit for PArticle Simulation (TOPAS) code. Pristine Bragg peak, spread out Bragg peak...
متن کاملShielding verification and neutron dose evaluation of the Mevion S250 proton therapy unit
For passive scattering proton therapy systems, neutron contamination is the main concern both from an occupational and patient safety perspective. The Mevion S250 compact proton therapy system is the first of its kind, offering an in-room cyclotron design which prompts more concern for shielding assessment. The purpose of this study was to accomplish an in-depth evaluation of both the shielding...
متن کاملA comparison of arrived dose to the heart in the treatment of breast cancer in different modes of proton radiation by proton therapy using Monte Carlo simulation
Introdution: Today, the Advantages of radiation therapy by charged particles is indicated for the treatment of cancerous. During the passing of proton beam in the body tissues, secondary particles produce, which penetrate to the body healthy tissues and cause damage. The aim of this research was calculating the Spread out Bragg Peak for covering the breast cancer and investigating arrived dose ...
متن کاملDose Assessment of Eye and Its Components in Proton Therapy by Monte Carlo Method
Introduction Proton therapy is used to treat malignant tumors such as melanoma inside the eye. Proton particles are adjusted according to various parameters such as tumor size and position and patient’s distance from the proton source. The purpose of this study was to assess absorbed doses in eyes and various tumors found in the area of sclera and choroid and the adjacent tissues in radiotherap...
