recent developments in brachytherapy source dosimetry
Authors
abstract
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 problem has been recently addressed by task group 43 (tg43) from the american association of medical physics (aapm) with a protocol for dosimetric characterizatio n of brachytherapy sources. this new protocol has been further updated using published data from international sources, by a new task group from the aapm. this has resulted in an updated protocol known as tg43u1 that has been published in march 2004 issue of medical physics. the goal of this presentation is to review the original tg43 protocol and associated algorithms for brachytherapy source dosimetry. in addition, the shortcomings of the original protocol that has been resolved in the updated recommendation will be highlighted. i am sure that this is not the end of the line and more work is needed to complete this task. i invite the scientists to join this task and complete the project, with the hope of much better clinical results for cancer patients. iran . j. radiat. res., 2004 2 (3): 97-105

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 ...

This work presents experimental dosimetry results for a new 103Pd brachytherapy seed, in accordance with the AAPM TG-43U1 recommendation that all new low-energy interstitial brachytherapy seeds should undergo one Monte Carlo (MC) and at least one experimental dosimetry characterization. Measurements were performed using TLD-GR200A circular chip dosimeters using standard methods employing thermo...

PURPOSE In this study, we attempted to obtain full dosimetric data for a new (90)Y brachytherapy source developed by the College of Chemistry (Sichuan University) for use in high-dose-rate after-loading systems. MATERIAL AND METHODS The dosimetric data for this new source were used as required by the dose calculation formalisms proposed by the AAPM Task Group 60 and Task Group 149. The active...

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...
