Emission Tomography (ET) covers a wide number of applications, from the standard clinical imaging to the more recent Hadrontherapy (HT) treatment monitoring. For all aforementioned applications different trends in detector have been explored, attempting at finding the optimal one. We present a comprehensive study of conventional and novel detector concepts, crystal based, employed for Positron Emission Tomography (PET) and Single Photon Imaging. ET employs crystal based detectors given their capability to merge high detection efficiency, good energy and spatial resolution with fast timing. We compare monolithic crystal detectors, an LaBr3 crystal block read out by a Silicon Photo-Multipliers matrix, and AX-PET, a novel detector with axially oriented crystals. The latter is based on individually read out LYSO crystals, 10 cm long, axially arranged. The potential of both devices, with respect to prompt gamma imaging and PET monitoring of HT treatments we'll be presented in detail. Defining the detector of choice over a wide dynamic range is one of the main objective of the presented work.
