Time-Of-Flight (TOF) is widely used in areas such as Positron Emission Tomography (PET). This technique can also be applied to other imaging systems such as Compton imaging. TOF information helps to determine the interaction order on the detector. This information can improve the image quality from Compton imaging. In this study, we build the TOF Compton detector using GFAG Crystal and a high time resolution front-end electronic circuit. In the TOF-PET system, we have achieved a 400 ps time resolution. We expect the TOF technique can be applied in the Compton camera.
