We aim to realize quantum PET (Q-PET) that performs diagnosis based on positronium (Ps) lifetime instead of positron distribution. There is a temperature distribution in the living body. The temperature differs between the surface and the depths of the body, but it is known that the Ps lifetime changes depending on the water temperature. In this study, we conducted an experiment to investigate its effect using a brain-dedicated clinical PET scanner VRAIN.
