A conventional Compton camera reconstructs initial gamma-rays direction as circle. A Compton gamma-ray camera which we have developed can detect electron tracks. So our camera can reconstruct the initial gamma-rays as arc. It makes getting the low noise of image. In this paper, we report the results of three version of electron tracking camera. One is 10 × 10 × 10 cm 3 Time Projection Chamber (TPC) as a scatter detector and 15 × 15 cm2 GSO pixel scintillator array (PSA) as an absorber. Second is a 10 × 10 × 10 cm3 TPC and a 10 × 10 cm2 LaBr3 PSA. The energy resolution of LaBr3 scintillator is about 2 times better than GSO scintillator. Third is a 30 × 30 × 15 cm3 TPC and a 30 × 30 cm2 GSO pixel PSA. The efficiency of this system is better than 10 cm3 cube Compton gammra-ray camera.
