Abstract
In modern radiotherapy, electron beams are used less and less often. However, there are still techniques where this type of particles is irreplaceable, like intraoperative radiotherapy (IORT) or total skin electron irradiation (TSEI). Due to low range of electrons penetrating the medium, dosimetric measurements and beam characteristics are challenging. One of the most important steps during this process is to select the right detector in order to collect reliable data. The purpose of this work was to perform beam characteristics using six commercially available detectors: Semiflex 3D (Type 31021), Advanced Markus (Type 34045), Markus (Type 23343), Roos (Type 34001), microDiamond (Type 60019), Diode E (Type 60017). Collected data shows various parameters describing electron beams, depending on the used detector. Obtained results showed that the most useful detector for beam characteristics is microDiamond Type 60019. Thanks to the very small effective volume, microDiamond showed a superior spatial resolution, which is especially handful during the measurements of dose profiles, allowing estimating beam parameters very precisely.
