Single source energy detector and data compensation method
The invention provides a single source energy detector and a data compensation method. The detector comprises a photon detector and an integral detector. The photon detector and the integral detector are arranged in a mixed mode and correspond to a radiation source, the integral detector works in an integral mode, the photon detector works in a photon counting mode, and the integral detector is used for compensating for the data lost in the photon detector due to counting saturation. One detector is adopted, but the two other detectors, namely the integral detector and the photon detector, are arranged in the array of the detector. The integral detector is used for compensating for the data lost in the photon detector due to saturation. Therefore, scanning time will not be increased because of additional reduction of a scanning dose, and the problem that when two detectors are in use, position matching is inaccurate because of different rotation sampling angles can be avoided. The single source energy detector can meet the requirements for both accuracy and time.
