Descripción
Sumario:A Compton telescope for dose monitoring in hadron therapy is under development at IFIC. The system consists of three layers of LaBr(3) crystals coupled to silicon photomultiplier arrays. (22)Na sources have been successfully imaged reconstructing the data with an ML-EM code. Calibration and temperature stabilization are necessary for the prototype operation at low coincidence rates. A spatial resolution of 7.8 mm FWHM has been obtained in the first imaging tests.
