Zusammenfassung:Preliminary results concerning the study of timing and energy resolution properties of recent Silicon Photomultipliers (SiPMs) devices by STMicroelectronics are here discussed in view of their possible applications in TOF PET modules and PET/MRI hybrid systems. A pair of devices with 60×60 microcells and an active area of 3.5×3.5mm2 have been coupled to 3×3×15mm3 LYSO crystals and fully characterized. Measurements of the linearity response with different gamma sources and of the timing resolution with the two 511keV photons from a 22Na positron source have been carried out.
