    "abstract": "We have studied the performance of two different types of front-end systems\nfor our gamma camera based on Hamamatsu H8500 (flat-panel 64 channels\nmulti-anode PSPMT) with a CsI(Tl) scintillator array. The array consists of 64\npixels of $6\\times6\\times20{\\rm mm}^3$ which corresponds to the anode pixels of\nH8500. One of the system is based on commercial ASIC chips in order to readout\nevery anode. The others are based on resistive charge divider network between\nanodes to reduce readout channels. In both systems, each pixel (6mm) was\nclearly resolved by flood field irradiation of $^{137}$Cs. We also investigated\nthe energy resolution of these systems and showed the performance of the\ncascade connection of resistive network between some PMTs for large area\ndetectors.",
