An investigation into the potential applicability of gel dosimeters for dosimetry in boron neutron capture therapy
Background: The aim of this work was to establish how well gel dosimeters performed, as substitutes for brain tissue compared with standard phantom materials such as water, polymethyl-methacrylate (or PMMA), A150 plastic and TE- liquid phantom material for dosimetry of neutron beams in boron neutron capture therapy. Materials and Methods: Thermal neutron fluence, photon dose and epithermal neu...
متن کاملThermoluminescent dosimeters (TLD) quality assurance network in the Czech Republic.
INTRODUCTION The Czech thermoluminescent dosimeters (TLD) quality assurance network was established in 1997. Its aim is to pursue a regular independent quality audit in Czech radiotherapy centres and to support state supervision. MATERIALS AND METHODS The audit is realised via mailed TL dosimetry. The TLD system consists of encapsulated LiF:Mg,Ti powder (type MT-N) read with Harshaw manual re...

متن کاملQuality Assurance test of the real-time beam tracking system
For radiotherapy with external beams, quality assurance (QA) of beam delivery is mandatory. Dynamical irradiation which changes parameters of beam delivery devices during the irradiation has to be assessed with a great caution. At GSI a dynamic beam delivery system, so called beam tracking system [1] was developed and integrated into the GSI therapy system [2] to irradiate moving tumours with i...
متن کاملReview of Fricke gel dosimeters
The innovation of adding a gel matrix to the traditional Fricke dosimeter to stabilize geometric information established the field of gel dosimetry for radiation therapy. A discussion of Fricke gels provides an overview of the issues that determine the dose response of all gel dosimeters in general. In this paper we review some of the features of Fricke systems to illustrate these issues and, i...
