ABSTRACT:
A method which evaluates at least one subject element includes detecting radiation from a plurality of elements including the subject element. Data pulses are provided which are representative of the detected radiation. A spectrum is derived from the data pulses and a shift of the spectrum is determined. The subject element is evaluated in accordance with the energy level of data pulses occurring in a region of interest associated with the subject element which are derived from with the spectrum and the determined shift of the spectrum.
