1. A method for determining the effective energy of an x-ray beam at a predetermined spatial location comprising the steps of:

  • providing an x-ray target incorporating a first and a second material having x-ray attenuation coefficients μ

    1 and μ

    2, respectively, which vary substantially similarly with variations in x-ray energy and a third material having an attenuation coefficient μ

    3 which varies at a faster rate than said first and said second materials as a function of x-ray energy;
