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 ...

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

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.

Development of a GPU-based Monte Carlo dose calculation code for coupled electron-photon transport

, 2010
Monte Carlo simulation is the most accurate method for absorbed dose calculations in radiotherapy. Its efficiency still requires improvement for routine clinical applications, especially for online adaptive radiotherapy.

Interventions for preventing oral mucositis for patients with cancer receiving treatment [PDF]

, 2003
Background: Treatment of cancer with chemotherapy is becoming increasingly more effective but is associated with short and long-term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them ...

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).

Towards the production of radiotherapy treatment shells on 3D printers using data derived from DICOM CT and MRI: preclinical feasibility studies [PDF]

, 2015
Background: Immobilisation for patients undergoing brain or head and neck radiotherapy is achieved using perspex or thermoplastic devices that require direct moulding to patient anatomy. The mould room visit can be distressing for patients and the shells
