Guided Noise Reduction for Spectral CT with Energy-Selective Photon Counting Detectors

● We created a joint bilateral filter for energy-selective detectors with encouraging first results. ● The SNR was improved from 3.3 to 72.3, while a low rRMSE is preserved and only little cross-talk between the channels is introduced.
