Abstract
A method of calibrating time in a Positron Emission Tomography (PET) device includes obtaining original time information and energy information of a first pulse signal collected by a detecting module during a scanning process of the PET device. A detector of the PET device includes a plurality of detecting modules. The original time information of the first pulse signal includes a moment at which an amplitude of the first pulse signal begins to be greater than a threshold. The method includes determining a pulse time calibration amount corresponding to the energy information of the first pulse signal according to stored information indicative of a correspondence between the pulse time calibration amount and the energy information of each detecting module. The method includes generating calibrated time information of the first pulse signal by calibrating the original time information with the pulse time calibration amount; and reconstructing a PET image based on the generated calibrated time information.
