Abstract

We are developing an electron-tracking Compton imaging camera (ETCC) based on a gaseous time projection chamber (TPC) and a scintillation camera. The ETCC detects the energy and the direction of the incident gamma ray using the information of the recoil electron and the scattered gamma ray. We have developed the ETCC with a detection volume of 23 times 28 times 15 cm³ which consists of the 23 times 28 times 15 cm³ gaseous TPC and 30 times 30 cm² GSO(Ce) scintillation camera. We obtained the gamma-ray image and investigated the performances of the ETCC. The angular resolution measure (ARM) and the scatter plane deviation (SPD) are 6.1 degree and 64.5 degree (HWHM) at 662 keV, respectively, and the energy resolution is 18.0% (FWHM) at 662 keV.
