Commissioning of a synchrotron-based proton beam therapy system for use with a Monte Carlo treatment planning system

Juan-Diego Azcona et al.

Summary: This work focuses on the commissioning and validation of a novel combination of a proton beam therapy system with a Monte Carlo treatment planning system. The research investigates various aspects including correcting measured depth-dose curves using Monte Carlo, modelling circular spot with a single Gaussian function, modelling range shifter, and validating the dose calculation model. The results show good agreement between measurements and calculations, indicating the accuracy and effectiveness of the proposed system.

Investigation into activation of accelerators at various synchrotron radiation facilities in Japan

Go Yoshida et al.

Summary: A large-scale activation survey was conducted at synchrotron radiation facilities in Japan to establish systematic guidelines for accelerator decommissioning. The results showed that the activation level was very low in all facilities, with concrete tunnels remaining unactivated and most beamline components either unactivated or minimally activated. Despite the high acceleration energy, the generation of radioactive waste was very low.

Peripheral Organ Equivalent Dose Estimation Procedure in Proton Therapy

Carles Domingo et al.

Summary: The aim of this study is to propose a reproducible methodology for evaluating the total equivalent doses in organs during proton therapy facilities. The methodology involves measuring the dose equivalent in representative locations inside an anthropomorphic phantom and using Monte Carlo simulation to obtain the neutron energy distribution. The results show that neutron is the main contributor to the total out-of-field dose equivalent, with a small contribution from photons, and the equivalent dose decreases as the organ is farther from the target volume.

Key biological mechanisms involved in high-LET radiation therapies with a focus on DNA damage and repair

Zacharenia Nikitaki et al.

Summary: DNA damage and repair studies are essential in radiation biology and play a crucial role in informing radiation therapy. The level and type of DNA damage are influenced by radiation dose and quality (LET), ultimately determining cell fate. Different modalities of radiation therapy have varying effects on DNA damage and repair mechanisms, impacting biological responses.

Roadmap: proton therapy physics and biology

Harald Paganetti et al.

Summary: Proton radiation therapy has become a mainstream treatment option for cancer, with almost 200 000 patients treated worldwide. Despite its advanced dose shaping capabilities, there are still challenges to address, including uncertainties, room for improvement in dose delivery, and biological effect differences compared to photon radiation. Additionally, the economic aspect of proton therapy, with its higher costs compared to conventional treatments, is also an area of active research.

Nuclear Reactions That Occur in Human Body During Proton Therapy

P. Sekowski et al.

Summary: Proton beams used in tumor treatment have a depth dose profile that saves healthy tissues. Proton therapy, with high biological effectiveness, shows promise in tumor radiotherapy. Measurement of secondary particles and their time in tissues can estimate their impact on therapeutic effects, while measuring decay of produced radionuclides allows estimation of tissue radioactivity.
