Recently, we have developed novel crystals such as Ce:GAGG and Ce:La-GPS, and up to now, we succeeded in growth of 2-inch-diameter bulk crystal. Here, Ce:La-GPS has a good light output of over 35,000 photons/MeV, good energy resolution of ~ 5% at 662 keV (FWHM) and no hygroscopic nature. As the next step, we have assembled a scintillation array camera with La-GPS pixel scintillators, and this array was coupled coupled to a Multi-Pixel Photon Counter (MPPC) array. We succeeded in obtaining the 2-dimension image in flood-field irradiation of gamma rays from a Cs-137 source, and each pixel was well-separated. In this presentation, we show the results of its gamma-ray imaging.
