7. A computer-implemented image processing method, comprising:
receiving energy resolved count data generated by a photon-counting detector;
transforming the energy resolved count data into transformed count data by applying one or more weights to the energy resolved count data, the weights being based on calibration image data for the photon-counting detector and the calibration image data for the energy integrating detector;
converting the transformed count data into through-material path length data to enable the photon-counting detector to emulate the energy integrating detector; and
outputting the through-material path length data.
