New insights on clinical perspectives of FLASH radiotherapy: from low- to very high electron energy

Frontiers in Oncology, 2023
Radiotherapy (RT) is performed in approximately 75% of patients with cancer, and its efficacy is often hampered by the low tolerance of the surrounding normal tissues.

Assessment of the quality of very high-energy electron radiotherapy planning [PDF]

Radiotherapy and Oncology, 2016
To assess the quality of very-high energy electron (VHEE) scanning pencil beam radiation therapy in relation to state-of-the-art volumetric modulated arc therapy (VMAT) and to determine the extent of its application.We planned five clinical cases with VHEE scanning pencil beams of 100 and 120MeV, equally distributed in a coplanar arrangement around the

Kimura's Disease of the Orbit Successfully Treated with Radiotherapy Alone: A Case Report

Case Reports in Ophthalmology, 2014
We performed radiotherapy in a 28-year-old patient with Kimura's disease of the orbit. Irradiation with 21.6 Gy was administered to the tumor bed with a single dose of 1.8 Gy in 5 weekly fractions delivered via a high-energy linear accelerator (6-MV X ...

Dosimetry for New Radiation Therapy Approaches Using High Energy Electron Accelerators

Frontiers in Physics, 2020
We have performed dosimetry studies using electron beams with energies up to 50 MeV, which exceed current clinical energy ranges and approaches the bottom end of the very high energy electron range. 50 MeV electron beams can reach deep-seated tumors.

Electron and Photon Energy Spectra Outside of 6 MV X-ray Small Radiotherapy Field Edges Produced by a Varian iX Linac

Frontiers in Physics, 2021
Due to the increase in the survival probability for patients treated with modern radiotherapy techniques to live enough for experimenting the late radiation effect, low dose outside the treatment volume becomes a concern.

Photoneutron production mechanisms, their characteristics, and shielding strategies in high-energy linac environment: A review

Journal of Radiation Research and Applied Sciences
Radiotherapy, a mainstay cancer treatment for patients worldwide, utilizes medical linear accelerators (linacs) with photon energies ranging from 4 MV to 25 MV. However, concerns arise at higher energies (>6 MV, particularly >10 MV).

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Risks posed by neutron contamination in high energy radiotherapy

Australasian Physical & Engineering Sciences in Medicine, 2017
Radiotherapy is a common cancer treatment which aims to use radiation energy to kill tumour cells without damaging healthy tissue. High energy x-rays penetrate tissue deeply, depositing most of their energy beyond the skin and shallow tissues. X-rays with energies above 8 MeV may interact to produce neutrons, to which the patient is then exposed ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
