GEC-ESTRO BRAPHYQS

The BRAchytherapy PHYsics Quality Assurance System (BRAPHYQS) working group of GEC-ESTRO was originally created under the ESQUIRE Project funded by the European Commission (Grant Agreement S12.322029 (2001CVG2-005) and SPC.2002480). The ESQUIRE Project ended in December 2003. The BRAPHYQS working group was in charge of Task 6 of the ESQUIRE project. One of the outputs was the publication of the ESTRO Booklet number 8 "A Practical Guide To Quality Control Of Brachytherapy Equipment". BRAPHYQS is supported by ESTRO and receives sponsorship from industry for its meetings. Since then BRAPHYQS works on different working packages in brachytherapy physics. Results are published in peer-reviewed journals. Typically two working meetings per year are organized to support the project work. Some of the working packages have involvement of other societies as AAPM or ABG.

A database of TG-43 dosimetry parameters of brachytherapy seeds/sources is stored at the Joint AAPM/IROC Houston Registry of Brachytherapy Sources webpage. All sources in this registry have direct or indirect traceability to the air-kerma strength standards maintained by accredited calibrations laboratories.

On the European side a TG-43 dosimetry parameter database for brachytherapy sources is maintained by BRAPHYQS in close cooperation with the University of Valencia. The AAPM/IROC and BRAPHYQS databases are streamlined and continuously updated when consensus data is available.  

The consensus dosimetry parameters presented in both databases have been obtained from TG-43, TG-43U1, TG-43U1-Errata, TG-43U1S1, TG-43U1S1-Errata, TG-43U1S2, TG-43U1S2-Errata, and HEBD reports. The links below redirect to spreadsheets in MS excel format with the consensus datasets. In addition, QA tables in Cartesian coordinates have been added to each source consistent with the TG-43 datasets.

BRAPHYQS consists of a core group of physics experts in brachytherapy. Depending on the running working package topics external experts are invited to participate in specific projects. Therefore, the list of participants changes from time to time (Including the TG43 members and consultants).
