Abstract
A dosimeter made with state of art polycrystalline Chemical Vapour Deposited (pCVD) diamond for applications in clinical radiotherapy has been manufactured, based on a large area (2.5 × 2.5 cm2) film equipped with a matrix of contacts. A dose profile under an Intensity Modulated Radiotherapy (IMRT) beam for prostate cancer has been monitored using a set of in-line pads along a section of the field map. Results compare well with data obtained with a commercial bidimensional silicon dosimeter, confirming that our pCVD diamond device is suitable for mapping the conformed dose in IMRT treatments.
