Comparison of 60Co and 192Ir sources in HDR brachytherapy
This paper compares the isotopes (60)Co and (192)Ir as radiation sources for high-dose-rate (HDR) afterloading brachytherapy. The smaller size of (192)Ir sources made it the preferred radionuclide for temporary brachytherapy treatments. Recently also (60)Co sources have been made available with identical geometrical dimensions. This paper compares the characteristics of both nuclides in differe...
متن کاملDose Distributions of an 192Ir Brachytherapy Source in Different Media
This study used MCNPX code to investigate the brachytherapy (192)Ir dose distributions in water, bone, and lung tissue and performed radiophotoluminescent glass dosimeter measurements to verify the obtained MCNPX results. The results showed that the dose-rate constant, radial dose function, and anisotropy function in water were highly consistent with data in the literature. However, the lung do...
متن کاملGafchromic film dosimetry of a new HDR 192Ir brachytherapy source
High-dose-rate (HDR) brachytherapy is a popular modality for treating cancers of the prostate, cervix, endometrium, breast, skin, bronchus, esophagus, and head and neck as well as soft-tissue sarcomas. Because of different source designs and licensing issues, there is a need for specific dosimetry dataset for each HDR source model. The main objective of the present work is to measure 2D relativ...
متن کاملComparison of the hypothetical 57Co brachytherapy source with the 192Ir source
AIM OF THE STUDY The (57)Co radioisotope has recently been proposed as a hypothetical brachytherapy source due to its high specific activity, appropriate half-life (272 days) and medium energy photons (114.17 keV on average). In this study, Task Group No. 43 dosimetric parameters were calculated and reported for a hypothetical (57)Co source. MATERIAL AND METHODS A hypothetical (57)Co source w...
متن کاملDetermination of Dosimetric Characteristics of IrSeed 125I Brachytherapy Source
Introduction Low dose rate brachytherapy sources have been widely used for interstitial implants in tumor sites, particularly in prostate. Dosimetric characteristics of a new IrSeed 125I brachytherapy source have been determined using the LiF thermoluminescent dosimeter (TLD) chips. Materials and Methods Dose rate constant, radial dose function, and anisotropy function around the IrSeed 125I so...
