عنوان انگلیسی Determination of Dosimetric characteristics of a New 192Ir-PDR Brachytherapy Source According to AAPM TG- 43 Protocol using Monte Carlo simulation technique
چکیده انگلیسی مقاله Introduction: 192Ir is one of the important sources frequently used in brachytherapy. Up to now, a lot of commercial models of this source have been made which Ir-192 has been recently added to them. The aim of the present study is to determine the dosimetric parameters of this new source model based on the recommendations of TG-43(U1) protocol using Monte Carlo simulation technique.   Materials and Methods: The assessed parameters included dose rate constant, radial dose function, anisotropy function, and dose distribution around the source. Calculations were performed in water phantom using MCNP4C Monte Carlo code. Results: The dose rate constant of this new source in water was 1.07+0.06 cGyh-1U-1 which was   in   a   good   agreement   with   the    TLD    measured    data    (1.13+0.07    cGyh-    1U-1). Conclusion: The results of this study showed that the dosimetric characteristics of this new brachytherapy source are comparable with those of other commercially available sources. Furthermore, the simulated parameters were in accordance with the previously measured ones. This means that the Monte Carlo simulated dosimetric parameters could be employed to obtain the dose distribution around this new brachytherapy source based on TG-43(U1) protocol.
