摘要
Absorbed dose to water is the most important unit for radiation therapy. In this report, we present the values of the absorbed dose to water in high energy photon beams delivered by the Elekta Synergy linear accelerator of the IBA Dosimetry measured by two secondary standard laboratories. The measurements have been performed for photon beams qualities (TPR20,10) of 0.69, 0.75 and 0.77 according to the IAEA TRS 398 protocol. The absorbed dose to water has been measured using cylindrical chambers, types PTW TN31010 and IBA Dosimetry FC65-G. Performance of each reference ionization chamber is assessed through En numbers, which are in good agreement with ISO 13528 requirements.
