Abstract

Traditional assessment methods don’t fit for photon-counting image (PCI) system because the output of PCI system is the number of photon instead of the gray value. Normalized mutual information is presented to assess Photon-counting image system performance and calculated based on improved 2D entropy for PCI system to provide the fidelity of PCI system. Probabilities of target classification error are introduced by Bayesian posterior probability classification method under the different fidelity conditions and the result confirms fidelity values. This method applied in the PCI experiments can reflect image fidelity and system performance well in different experiment conditions and supplies the evidences for assessing the quality for photon-counting image.
