Double photon emission nuclides, such as In111, Cs134 and Co60, can be applied for DPECT imaging. DPECT is one of Compton imaging method, which includes detection of both of two gamma-rays from nuclides with two Compton camera. DPECT can detect gamma-ray source position with higher signal-to-noise ratio than conventional Compton imaging. In this research, we used two Compton cameras with Ce:GAGG scintillator for DPECT, and compared between DPECT imaging and conventional Compton imaging.
