چکیده
P Introduction ermanent seed-implant treatment using I radionuclide is currently a standard procedure for early-stage prostate carcinoma, and the method is now considered comparable to external-beam radiation therapy and prostatectomy. As with external beam radiation therapy, permanent seed implant treatment of the prostate requires a dose-outcome correction, pointing out the importance of the planning process. The positions and number of seeds are selected using the treatment planning system to achieve the best dose coverage of the prostate. The dose, calculated in accordance with the formalism Original Contribution Kitasato Med J 2011; 41: 136-144

Estimation of dosimetric parameters of I-125 brachytherapy source model 6711 using GATE8.1 code
Brachytherapy is one type of internal radiation therapy where radiation sources, which are usually encapsulated are placed as close as possible to the tumor site inside the patient's body. In this technique, it is important to determine dose distribution around the brachytherapy capsule. Hereby, in this paper, dosimetric parameters of I-125 brachytherapy source model 6711 are estimated accordin...

Introduction: Brachytherapy is one type of internal radiation therapy where radiation sources, which are usually encapsulated, are placed as close as possible to the tumor site or inside the patient's body. In this technique, it is important to determine dose distribution around the brachytherapy capsule to create optimal treatment plant. In this way, dosimetric parameters are...
متن کاملThe Effect of Scattering from Leg Region on Organ Doses in Prostate Brachytherapy for 103Pd, 125I and 131Cs Seeds
Introduction Dose calculation of tumor and surrounding tissues is essential during prostate brachytherapy. Three radioisotopes, namely, 125I, 103Pd, and 131Cs, are extensively used in this method. In this study, we aimed to calculate the received doses by the prostate and critical organs using the aforementioned radioactive seeds and to investigate the effect of scattering contribution for the ...
متن کاملAssessment of absorbed dose uncertainty of prostate due to source relocating in brachytherapy by monte carlo method
Brachytherapy, is a method to treat prostate cancer in which a radiation source is placed inside or next to the cancer affected tissues. Purpose of this article is to determine the uncertainty level of received dose in prostate tissue due to the relocation of the placed radiation sources and inflation in prostate after positioning the radiation seeds. To simulate the model 6711 Amersham (activi...
متن کاملStudy of Different Tissue Density Effects on the Dose Distribution of a 103Pd Brachytherapy Source Model MED3633
Introduction: Clinical application of encapsulated radioactive brachytherapy sources has a major role in cancer treatment. In the present research, the effects of different tissue densities on the dose distribution of a 103Pd brachytherapy source in a spherical phantom of 50 cm radius have been studied. Material and Methods: As is well known, absorbed dose in tissue depends to its density, but ...
