Dosimetric evaluation of electron beam Monte Carlo isodoses distribution based on thermoluminescent dosimetry

open access: diamondBrazilian Journal of Radiation Sciences, 2020
Electron beams are applied in radiotherapy treatments where superficialized doses are desirable as well as deeper tissues sparing. Monte Carlo method has been recently implemented in the TPS as the algorithm for electron beam isodoses calculation at the ...

Thermoluminescent composites of sintered synthetic-topaz/in situ corundum for dosimetry by a novel reversible process [PDF]

open access: goldHeliyon
Topaz (Al2F1·44(OH)0·56SiO4)/corundum (Al2O3) composites were prepared by a facile and novel reversible process from the sintering of synthetic topaz and AlF3 powders, with corundum formed in situ into the topaz matrix.

The Spinning Manny Indexed Overlay System for VMAT total body irradiation. [PDF]

open access: yesJ Appl Clin Med Phys
Abstract Purpose While modern intensity‐modulated techniques for total body irradiation (TBI) offer superior organ sparing and improved dose coverage compared to conventional TBI, their complexity has limited widespread adoption. Specifically, when treating individuals with Volumetric Modulated Arc Therapy (VMAT‐TBI), a transition between the head ...

On the spectral changes of magna-field photon beams used in total body irradiation and impact on dosimetry. [PDF]

open access: yesJ Appl Clin Med Phys
Abstract Purpose Accurate dosimetry for magna fields can be challenging when dosimeters exhibit energy dependence. The aim of this work was to use Monte Carlo (MC) simulations to calculate energy spectra of magna photon fields and use the spectral information to derive energy dependence correction factors for commonly used dosimeters.

First experience with third-party validations: A robust calibration and QA procedure for proton FLASH delivery. [PDF]

open access: yesJ Appl Clin Med Phys
Abstract Background Proton FLASH radiotherapy, delivering ultra‐high dose rates, shows promise in reducing normal tissue toxicity while maintaining tumor control. However, accurate dosimetry and quality assurance (QA) for FLASH remain challenging due to the extreme dose rates involved.
