Abstract:
1. An imaging system, comprising: a projection data providing unit for providing energy-dependent first projection data of a region of interest; and an attenuation component image generation unit to generate a first attenuation component image of the region of interest and a second attenuation component image of the region of interest, where the first attenuation component image and the second attenuation component image are generated by generating energy-dependent second projection data from the energy-dependent first projection data using a model that extracts a first attenuation data set from the energy-dependent first projection data and that extracts a second attenuation data set from the energy-dependent first projection data, where the energy-dependent second projection data includes the first attenuation data set and the second attenuation data set, and where deviations of the second projection data from the first projection data are minimized.
