Continuous scintillator crystals can offer several advantages over pixellated crystals. Apart from an increase of the active volume, spatial resolution is not limited to the crystal size and Depth of interaction (DoI) can be estimated from the light distribution. Continuous crystals coupled to finely segmented photodetectors can improve simultaneously spatial resolution and sensitivity, the main two...
A three layer Compton telescope for dose monitoring in hadron therapy has been developed at IFIC. It consists of three detector layers and each layer is made of a continuous LaBr3 crystal coupled to four silicon photomultiplier (SiPMs) arrays. A dedicated image reconstruction method has also been developed. The telescope has been characterized and tested with radioactive sources and in-beam. Simulations...
A high resolution PET detector head for small animal PET applications has been developed. The detector is composed of a 12mm×12mm continuous LYSO crystal coupled to a 64-channel monolithic SiPM matrix from FBK-irst. Crystal thicknesses of 5mm and 10mm have been tested, both yielding an intrinsic spatial resolution around 0.7mm FWHM with a position determination algorithm that can also provide depth-of-interaction...
