An optical computed tomography scanner for three dimensional gel dosimetry of radiotherapy dose distributions
… must be validated by measurement to ensure correct patient treatments. Traditional radiotherapy dosimeters do not measure dose entirely in 3D. They effectively ‘spot check’ accuracy at discrete points or planes, without the ability to fully visualise measured dose distributions in true 3D. True …

Characterization of The New Xoft Axxent Electronic Brachytherapy Source Using Presage(Tm)
… advances in the burgeoning field of electronic brachytherapy, an accurate method of 3D dosimetry is needed to ensure understanding of dose distributions, which can improve patient care. The aim of this study was to characterize the Xoft Axxent electronic brachytherapy source using …

Quality Assurance of Advanced Treatment Modalities Using Presage® Dosimeters
… intended calculated dose is being delivered correctly using current techniques that are 2D-based because the resultant dose distributions can differ markedly in various sections of the target. A measurement of composite dose from the entire plan should be included in patient-specific IMRT QA. A …
