A focused very high energy electron beam for fractionated stereotactic radiotherapy

open access: yesScientific Reports, 2021
An electron beam of very high energy (50–250 MeV) can potentially produce a more favourable radiotherapy dose distribution compared to a state-of-the-art photon based radiotherapy technique.

An experimental study of focused very high energy electron beams for radiotherapy

open access: yesCommunications Physics, 2021
Very high energy electrons (VHEE) penetrate deeply in tissues and can provide an alternative to photon irradiation for tumour treatment. Using VHEE beams at CERN Linear Electron Accelerator for Research (CLEAR) focused into a water phantom, the authors ...

A compact, lightweight, variable-energy cyclotron for conventional and FLASH ion beam radiotherapy [PDF]

open access: yesFrontiers in Oncology
IntroductionThe advantage of ion beam radiotherapy for cancer lies in its low dose proximal and distal to the tumor, owed to an energy-dependent depth-dose profile, the Bragg-peak. However, conventional techniques to achieve different energies often rely

Evaluation and Comparison of Dosimetric Characteristics of Semiflex®3D and Microdiamond in Relative Dosimetry under 6 and 15 MV Photon Beams in Small Fields [PDF]

open access: yesJournal of Biomedical Physics and Engineering, 2022
Background: In modern radiotherapy techniques, the frequently small and non-uniformed fields can increase treatment efficiency due to their highly conformal dose distribution.

Impact of Different Beam Energies on The Incidence of Thyroid Cancer in Breast Cancer Radiotherapy

open access: yesFrontiers in Biomedical Technologies, 2022
Purpose: During breast radiotherapy, the organs which are located out of the radiation field such as the thyroid are prone to secondary cancers. The present study aims to evaluate the risk of thyroid cancer in breast cancer radiotherapy in conventional ...

Analysis of physical dose enhancement in nano-scale for nanoparticle-based radiation therapy: a Cluster and endothelial cell model [PDF]

open access: yesNanomedicine Journal, 2021
Objective(s): One major difficulty of conventional radiotherapy is the lack of selectivity between the tumor and the organs at risk. In nanoparticle aided radiotherapy, heavy elements are present at higher concentrations in the tumor than normal tissues.
