Implementation of a QC procedure based on the absolute dosimetry of 192Ir-HDR sources by micro-ioniziaton chamber

The purpose of this report is to establish a method for the direct measurement of the absorbed dose delivered by 192 Ir high--dose-rate (HDR) brachytherapy (BT) sources using a PinPoint ionization chamber.After a literature review, a quality control procedure for the absorbed dose-in water has been developed and included in the quality assurance (QA) of the brachyhterapy unit GammaPlus iX (Varian Medical Systems, Palo, CA).
