Polycrystalline CVD diamond dosimeters for Intensity Modulated Radiotherapy (IMRT)

Diamond has a potential for Intensity Modulated Radiotherapy (IMRT) applications, being a solid-state nearly tissue equivalent material, with the possibility to be grown in large diameter wafers by Chemical Vapour Deposition (CVD). We present a monolithic polycrystalline CVD diamond dosimeter and first results in an IMRT beam. Our device shows to be able to cope with the complex temporal/spatial structure of the IMRT field.
