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 کاملRecent developments in brachytherapy source dosimetry
Application of radioactive isotopes is the treatment of choice around the globe for many cancer sites. In this technique, the accuracy of the radiation delivery is highly dependent on the accuracy of radiation dosimetry around individual brachytherapy sources. Moreover, in order to have compatible clinical results, an identical method of source dosimetry must be employed across the world. This ...
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×...
متن کاملRecent developments in brachytherapy source dosimetry
rachytherapy, the treatment of cancer patients by placing sealed radioactive elements at the short distances relative to the tumor, was born soon after Henri Becquerel’s discovery of radioactivity in Paris (1896) and Marie Curie’s discovery of radium (1898). However, within the past several years there have been great improvements in the technical aspect of the brachytherapy procedures (Blasko ...
