TL;DR: An overview of the current state of developments of radiotherapy with FLASH electrons and protons, very high energy electrons as well as laser-driven particles and the related challenges in dosimetry due to the ultra-high dose rate during the short radiation pulses is given.
Journal ArticleDOI
The practical application of scintillation dosimetry in small-field photon-beam radiotherapy
TL;DR: The suitability of the plastic scintillation detector Exradin W1 for clinical dosimetry under stereotactic conditions, in particular the tried and tested procedures for CLR determination, output factor measurement and automated dose profile scans in water phantoms, have been confirmed.
Journal ArticleDOI
Experimental determination of the recombination correction factor kS for SNC 125c, SNC 350p and SNC 600c ionization chambers in pulsed photon beams.
TL;DR: The method proposed by Burns & McEwen was used in this study to determine the coefficients γ and δ used for the calculation of the correction factor ks of three ionization chambers for an absorbed dose to water range of 0.2mGy to 1.6mGy per pulse in pulsed photon beams.
Journal ArticleDOI
Corrections of photon beam profiles of small fields measured with ionization chambers using a three-layer neural network.
TL;DR: In this article, a feed-forward neural network (NN) was used to deconvolution the beam profiles of very small photon fields collected with ionization chambers of various sizes.
Journal ArticleDOI

TL;DR: It was demonstrated that the Aerrow probe-type graphite calorimeter can be used for relative and absolute dosimetry in water in an UHPDR electron beam, to the author's knowledge, this is the first reported use of an absorbed dose calorimeters for an in-water percentage depth dose curve measurement.
