Computational study of the effect of focusing on VHEE radiotherapy

, 2023
Cancer is an increasingly relevant public health problem on the world stage. For it’s treatment, some types of radiotherapy are used, in order to deliver, through the use of beams of ionizing radiation, a quantity of dose in the tumor region while ...

Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry. [PDF]

Adv Mater
Silicon has been a cornerstone material of radiation therapy dosimetry for many decades, providing somewhat unchallenged performance. However, there are caveats to its use, requiring complex designs and, often, correction factors to provide accurate measurements.

Very high‐energy electron ( VHEE ) beams in radiation therapy; Treatment plan comparison between VHEE , VMAT , and PPBS

Medical Physics, 2017
The aim of this study was to evaluate the performance of very high-energy electron beams (VHEE) in comparison to clinically derived treatment plans generated with volumetric modulated arc therapy (VMAT) and proton pencil beam scanning (PPBS) technology.

Evaluating VHEE radiotherapy treatment plans for prostate and lung cancer

, 2023
Over 50% of cancer patients will receive radiotherapy treatment at least once. Most patients are receiving photon radiotherapy. In this work very high energy electron (VHEE) radiotherapy is being studied as a potential replacement for photon radiotherapy.

Standard requirements for clinical very high energy electron and ultra high dose rate medical devices

Frontiers in Physics
Very High-Energy Electrons (VHEE) present a promising innovation in radiation therapy (RT), particularly for the treatment of deep-seated tumors using Ultra High Dose Rate (UHDR) within the framework of FLASH-RT.

Beam optics study for a potential VHEE beam delivery system [PDF]

, 2022
VHEE (Very High Energy Electron) therapy can be superior to conventional radiotherapy for the treatment of deep seated tumours, whilst not necessarily requiring the space and cost of proton or heavy ion facilities.

Laser-plasma generated very high energy electrons (VHEEs) in radiotherapy [PDF]

SPIE Proceedings, 2017
As an alternative modality to conventional radiotherapy, electrons with energies above 50 MeV penetrate deeply into tissue, where the dose can be absorbed within a tumour volume with a relatively small penumbra. We investigate the physical properties of VHEEs and review the state-of-the-art in treatment planning and dosimetry. We discuss the advantages

Dosimetry and radioprotection evaluations of very high energy electron beams

Scientific Reports, 2021
Very high energy electrons (VHEEs) represent a promising alternative for the treatment of deep-seated tumors over conventional radiotherapy (RT), owing to their favourable dosimetric characteristics.

First theoretical determination of relative biological effectiveness of very high energy electrons

Scientific Reports, 2021
Very high energy electrons (VHEEs, E > 70 MeV) present promising clinical advantages over conventional beams due to their increased range, improved penumbra and relative insensitivity to tissue heterogeneities.
