High Spatial Resolution Silicon Detectors for Dosimetry in Moving Target Radiotherapy

Radiotherapy benefits half of all cancer patients in the management of their disease. Several studies have shown dose escalation and hypofractionation leads to better tumour control for lung and prostate cancers. The large dose encountered in these treatments has the potential to increase toxicity to surrounding organs, especially for lung and prostate patients, due to tumour motion during treatment. The limiting factor for expanding the use of techniques such as stereotactic ablative radiotherapy (SABR) is toxicity.
