AbstractHadron therapy (HT) is a technique used in cancer treatment that consists in the irradiation of tumours using light ions or protons instead of photons. HT treatment monitoring in real-time is one of the main challenges addressed nowadays. The IRIS group (http://ific.uv.es/iris) at IFIC-Valencia is developing a Compton telescope with this purpose. The system is made of three LaBr3 detector planes coupled to silicon photomultipliers (SiPMs). A first prototype (MACACO: Medical Applications CompAct COmpton camera) was successfully developed, with promising results. A second version has been developed with the aim of improving the system performance, including new detectors for the first two planes and an improved image reconstruction code, improving significantly the performance tests in laboratory and accelerator facilities. The performance improvement of MACACO II was verified through experimental tests. In addition, Monte Carlo simulations were made with GATE v 7.0 getting a good correlation with the experimental measurements. In this poster we present results corresponding to the two-layer layout with the new detectors.
