Abstract
System and method for determining an energy window in a medical imaging system. The imaging system, designed to operate in a single photon counting mode, includes a pixilated radiation detector having an array of detector elements coupled to respective electronic channels. The method includes measuring the electronic signals produced for each detector element and producing two spectra corresponding to two different energy levels of photons, deriving an electrical offset for the signals received from each detector element and producing corrected signals and a corrected spectrum of radiation flux impinging on the detector, calculating a peak channel value measured in units of energy channels, and determining an energy window for each detector element such that the width of the window is equal to a desired fraction of the peak channel value.
