Quality Assurance for Radiation Therapy in Belgium Based on Alanine/ESR dosimetry


In Belgium, a project started this year for quality assurance in radiotherapy, the so-called BeldART project (Belgian dosimetry audits in radiotherapy). The dosimetry measurement system employed by the Belgian group located at the NUTEC centre of the XIOS Hogeschool in Diepenbeek, Belgium, is based on the detection of radiation-induced free radicals in alanine by electron spin resonance (ESR). Methods and software were adapted to the special requirements within the framework of a collaboration with the PTB. Parts of the measurement system used were developed at PTB, e.g. the probe holder for the spectrometer and the software for the data evaluation.
