Recent 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 ...

Recent 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 ...

Thermoluminescent and Monte Carlo dosimetry of IR06‐P103d brachytherapy source

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...

Monte Carlo dosimetry of a new 90Y brachytherapy source

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...

Gafchromic 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...
