Abstract
An energy discriminator, for distinguishing between high and low x-ray energies in a energy sensitive x-ray machine divides high energies into asymmetric regions. The flux rates in each of the asymmetric regions being used to locate the high-energy region in the appropriate high-energy location even in regions of spectral monotonicity. Because two clearly defined spectral peaks need not be present for accurate location of spectral regions in the output of the detector, less filtering and lower tube loading is required.
