description The invention relates to an image correction method, device and system based on PET scanning, computer equipment and a computer readable storage medium, and the method comprises the steps: obtaining an actual measurement coincidence counting chord graph obtained based on PET scanning; obtaining a true coincidence event simulation chordal graph, a scattering coincidence event simulation chordal graph and an instantaneous gamma ray event simulation chordal graph based on Monte Carlo simulation; fitting the actually measured coincidence counting chord graph by using the true coincidence event simulation chord graph, the scattering coincidence event simulation chord graph and the instantaneous gamma ray event simulation chord graph to generate a first scattering and instantaneous gamma correction sine graph; and performing image correction on the PET image based on the first scattering and the instantaneous gamma correction sinogram. According to the invention, the complexity of instantaneous gamma ray estimation
