1. A method of operation in an imaging system, the imaging system having a radiation detector including a monolithic scintillator, the radiation detector having deadtime associated therewith, the method comprising:

  • generating data of an object in response to radiation detected by the detector, including collection of deadtime data associated with the detector while generating said data of the object;

    correcting said data of the object for said collected deadtime data, including correcting said, data of the object for spatial variations in said collected deadtime data across an imaging area of the monolithic scintillator; and

    generating an image of the object based on the corrected data.
