Catalogue of X-ray energy spectra of electronic brachytherapy (eBT) device Papillon 50 manufactured by Ariane Medical Systems

The catalogue was compiled from suitable data available in literature and from the data measured or created by the project "18NRM02 PRISM-eBT" (Primary standards and traceable measurement methods for X-ray emitting electronic brachytherapy devices; http://www.ebt-empir.eu/) of the European Metrology Programme for Innovation and Research (EMPIR).

 

The main goal of the catalogue was to develop a set of harmonised reference X-ray qualities denoted as “eBT equivalent” that would be established for in-laboratory activities by the X-ray tubes usually available for calibration in calibration laboratories, but the tube voltage and the filter are specifically selected to simulate the energy spectrum of the corresponding eBT radiation as closely as possible at the reference point.

 

The catalogue contains the following spectra:

1) X-ray photon fluence eBT spectra measured and/or Monte Carlo simulated in air and/or in water, whenever they were available;

2) eBT-equivalent X-ray photon fluence spectra that match selected eBT spectra. Typically, the eBT-equivalent spectra were calculated by a dedicated software, usually SpekPy software. If available, the eBT-equivalent spectra already realized are also included. Please note that the eBT-equivalent spectra may be site-dependent, based on properties of X-ray generator available (anode angle, inherent filtration) and the distance from anode to measurement point (attenuation in air). Realized eBT-equivalent spectra should be validated by spectrometry.
