Within the Joint Research Project PRISM-eBT to establish primary standards and traceable measurement methods for electronic brachytherapy devices (eBT), three different devices were spectrometrically investigated: the “Intrabeam®”-system from Carl Zeiss Medit...

Precise knowledge of high-energy photon spectra from clinical linear accelerators (linacs) is important for dosimetry in radiotherapy. High-energy photon spectra cannot be measured directly, so alternative methods are required. In this work, the spectral flue...

To determine the Type-B uncertainty of dose calculations using a Monte-Carlo model of a clinical linac and to quantify the contributions of different sources of uncertainty.
