Abstract
The disclosure relates to a system and method for determining a working bed location. The method may include: acquire a first reference bed location relating to a bed for supporting an object; acquire a first set of reference emission data relating to photons of a first energy level originated from radiation of scintillator crystals of a plurality of detectors, the first set of reference emission data corresponding to the first reference bed location; acquire, at a working bed location relating to the bed, a set of positioning emission data relating to photons of the first energy level, wherein the set of positioning emission data relating to photons of the first energy level originated from radiation of scintillator crystals of the plurality of detectors; and determine the working bed location based on the first reference bed location, the first set of reference emission data, and the set of positioning emission data.
