Abstract

This study focused on modeling a rotational radiosurgery system, specifically the Gamma ART-6000, utilizing Geant4 simulation. The simulation process involved calculating the dose distribution within a water phantom with an 8 cm radius, aimed at investigating beam characteristics for validating simulation geometry. The evaluation of radiosurgery dosimetry parameters, such as dose profiles, field size, penumbra width, and output factor for four different field sizes (4 mm, 8 mm, 14 mm, and 18 mm), demonstrated a high level of agreement with previous experimental data. Notably, the methodology employed for simulating the motion of the rotary radiosurgery system in this study exhibited good agreement compared to prior investigations.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
