Abstract
A time correction device for a PET system comprises a detector ring, a ring-shaped prosthesis, and detection, data acquisition, data coincidence, time shift calculation, data correction application modules. Center of the ring-shaped prosthesis overlaps with axial and radial center of the detector ring. The detection module is located in ring-shaped prosthesis. Center of the detection module is at the center of the ring-shaped prosthesis. The data acquisition module comprises data gathering and energy filtering modules connected to each other. The data gathering module comprises detectors and the detection module. The energy filtering module connects to the data gathering module receiving single-event time information. The data coincidence module is connects to the energy filtering module receiving the single-event time information. Time shift calculation module connects to the data coincidence module providing a shift value of the detectors. The data correction application module applies the shift value to the PET system.
