ABSTRACT
Permanent implantation of the iodine-125 brachytherapy sources is an irradiation technique for the treatment of the localized cancer. As described by the American Association of Physicists in Medicine (AAPM) Task group 43 (TG-43U1), it is crucial to determine the dose distribution around the brachytherapy seed before its effective clinical practice or even before releasing the sources for the treatment. In the present work, according to TG-43U1 report, the dosimetric parameters of BEBIG iodine-125 Low Dose Rate brachytherapy IsoSeed® I25.S06 source model was investigated. To perform the dose calculations, we have used GEANT4 Application for Emission Tomography (GATE) Monte Carlo simulations. Interesting results have been found. In particular, the dosimetric quantities like the radial dose function gL(r), the anisotropy function F(r,θ) and the dose rate constant Λ have been obtained. In addition, our data are in good agreement with the previous published works. It is also remarked that, GATE Monte Carlo code reproduces accurate dosimetric parameters results.
