SU-E-T-319: Monte Carlo Characterization of a New Directional Pd-103 High Dose Rate Source for Brachytherapy Application.
PURPOSE Standard brachytherapy sources emit radiation in a non-preferential direction away from the source. Though treatment outcomes are good, this can lead to late skin and subcutaneous toxicities in sensitive structures. Proposed low dose rate directional sources for interstitial brachytherapy, showed to have an improvement in the dose uniformity within the subcutaneous volume, reduction in ...
متن کاملExperimental and Monte Carlo dosimetric characterization of a 1 cm (103)Pd brachytherapy source.
PURPOSE To determine the in-air azimuthal anisotropy and in-water dose distribution for the 1 cm length of a new elongated (103)Pd brachytherapy source through both experimental measurements and Monte Carlo (MC) simulations. Measured and MC-calculated dose distributions were used to determine the American Association of Physicists in Medicine Task Group No. 43 (TG-43) dosimetry parameters for t...
متن کاملPSEUDO-RANDOM DIRECTIONAL SEARCH: A NEW HEURISTIC FOR OPTIMIZATION
Meta-heuristics have already received considerable attention in various fields of engineering optimization problems. Each of them employes some key features best suited for a specific class of problems due to its type of search space and constraints. The present work develops a Pseudo-random Directional Search, PDS, for adaptive combination of such heuristic operators. It utilizes a short term...
متن کاملDetermination of Dosimetric Parameters of the Second Model of Pd-103 Seed Manufactured at Agricultural, Medical and Industrial Research School
Introduction: The use of low energy isotopes such as 103 Pd in brachytherapy for the treatment of cancers such as prostate, eye, head, neck, breast and cervix is increasing. In this regard, different models of Pd- 103 seeds have been designed and manufactured at the Agricultural, Medical and Industrial Research School (AMIRS) of Atomic Energy Organization of Iran. In this resear...
متن کاملDose distribution and dosimetry parameters calculation of MED3633 palladium-103 source in water phantom using MCNP
Background: Palladium-103 (103Pd) is a brachytherapy source for cancer treatment. The Monte Carlo codes are usually applied for dose distribution and effect of shieldings. Monte Carlo calculation of dose distribution in water phantom due to a MED3633 103Pd source is presented in this work. Materials and Methods: The dose distribution around the 103Pd Model MED3633 located in the center of 30×...
