A Compton telescope prototype for dose monitoring in hadron therapy has been developed. The camera is based on continuous LaBr3 and LYSO crystals coupled to silicon photomultipliers for detection and readout respectively. The setup consists of a 16x18x5 mm3 LaBr3 crystal coupled to a 16x18 mm2 MPPC array as a first layer of the telescope, and a 12x12x5 mm3 LYSO crystal coupled to another 16x182 mm MPPC array as a second layer. The SPIROC1 ASIC is employed as readout electronics. The first coincidence tests have been successfully carried out and allow the reconstruction of a point-like source, in different positions, encouraging the development and the improvement of the prototype to a full imaging system.
