ABSTRACT:
An emission tomographic system for imaging an object of interest is described. The system, in one form, includes a gantry and a patient table. A detector including a collimator is secured to the gantry, and a computer is coupled to the gantry and to the detector to detect and control the position of the detector relative to the table. The system is configured to determine a transmission measurement and generate a scatter fraction utilizing the transmission measurement. A dual energy window data acquisition algorithm then determines non-scatter photons in a primary energy window utilizing the scatter fraction.
