A key component to the accurate delivery of radiation therapy is knowing exactly what dose the beam is producing. This can be achieved by measurement with ionization chambers, diodes, or other means.
However, as technology improves and radiotherapy equipment becomes ever more complex, some of the ‘gold standard’ measurement techniques that have been around for a century become unsuitable, and we must therefore design new detectors which can deal with the new technology.
At QUT our researchers work with radiotherapy clinics to develop new radiation detectors, including 3D gel dosimeters, to modify existing radiation detectors for use in new situations, and to characterise how radiation detectors respond to high energy beams produced by state of the art equipment.
