英文摘要	In this paper, we present a novel projection-based novel noise reduction method for photon counting energy resolving detectors in Spectral Computed Tomography (CT) imaging. In order to denoise the projection data, a guidance image from all energy channels is computed, which employs a variant of the joint bilateral filter to denoise each energy bin individually. The method is evaluated by a simulation study of cone beam CT data. We achieve a reduction of noise in individual channels by 80% while at the same time preserving edges and structures well in the results, which indicate that the methods are applicable to clinical practice.; CPCI-S(ISTP); yanye.lu@fau.de; 137-142
