摘要:
An apparatus and a method are provided for calculating an output spectrum of a photon-counting detector based on an incident spectrum. The apparatus includes processing circuitry to determine a plane extending from a top face of the photon-counting detector that includes regions that all possible incident rays will transverse divide the determined plane into subregions calculate a detector response function for each of the subregions determine an overall detector response function by summing the calculated detector response function for each of the subregions and normalizing the summation by an area of the determined plane and calculate the output spectrum based on the overall detector response function and the incident spectrum.
