Dose distribution response in HDRB measured with EBT2 and compared with PLATO SYSTEM

Dose distribution of a High Dose Rate Brachytherapy (BHDR) oncological treatment with 192Ir was measured using a Gafchromic EBT2 film. The film calibration was performed with a 60Co unit and a LINAC of 6 mV and 18 mV. Gafchromic behavior of a dosimeter varies in respect of energy. Experimental results of dose distribution match with those planned in the PLATO commercial system, they also show that there is a difference of 2.11% between the planning system and isodoses measured.
