Abstract
Methods, devices and systems for correcting a count loss in a Position Emission Computed Tomography (PET) system are provided. In one aspect, a method includes: constructing a virtual system including a plurality of virtual crystals, determining, for each of virtual Lines of Response (LORs) in the virtual system, a plurality of real LORs corresponding to the virtual LOR in the PET system, each of the real LORs corresponding to a scanning state of the PET system with a continuous incremental scanning mode, determining a count loss correction factor of the corresponding real LOR in each of the scanning states, determining a count loss correction factor of the virtual LOR according to the determined count loss correction factors of the plurality of real LORs corresponding to the virtual LOR, and performing count loss correction for the virtual LOR according to the determined count loss correction factor of the virtual LOR.
