Abstract
A Geant4 Monte Carlo simulation study was carried out to characterise a novel silicon strip detector, the Dose Magnifying Glass (DMG), for use in proton therapy Quality Assurance. We investigated the possibility to use DMG to determine the energy of the incident proton beam. The advantages of DMG are quick response, easy operation and high spatial resolution. In this work we theoretically proved that DMG can be used for QA in the determination of the energy of the incident proton beam, for ocular and prostate cancer therapy. The study was performed by means of Monte Carlo simulations Experimental measurements are currently on their way to confirm the results of this simulation study.
Highlights
While proton radiotherapy has experienced a growth in the number of operational facilities and an increase in capabilities of beam delivery technology, there has been a substantial lack of development in commercial detectors for related Quality Assurance (QA)
Detectors used in proton therapy QA should provide sub-millimetre spatial resolution determination of proton range over a wide energy range to resolve the steep energy gradient of the Bragg Peak and be able to provide this information at a sub-second temporal resolution
It is a miniature detector for use in proton therapy QA, with applications into X-ray stereotactic radiosurgery (SRT) and intensity modulated radiotherapy (IMRT) investigated previously demonstrating the Dose Magnifying Glass (DMG) capability to provide submillimetre spatial resolution at a sub-second temporal resolution over a large (103) dynamic range [4]
Summary
While proton radiotherapy has experienced a growth in the number of operational facilities and an increase in capabilities of beam delivery technology, there has been a substantial lack of development in commercial detectors for related Quality Assurance (QA). The Dose Magnifying Glass (DMG) is a silicon strip detector developed by the Centre of Medical Radiation Physics (CMRP) at the University of Wollongong. It is a miniature detector for use in proton therapy QA, with applications into X-ray stereotactic radiosurgery (SRT) and intensity modulated radiotherapy (IMRT) investigated previously demonstrating the DMG capability to provide submillimetre spatial resolution at a sub-second temporal resolution over a large (103) dynamic range [4]. Its advantages over existing commercial QA detectors include the simple device operation and high spatial resolution over a wide dynamic energy range, required to resolve the Bragg Peak accurately
