Fig. 3From: Virtual monoenergetic images from photon-counting spectral computed tomography to assess knee osteoarthritisRight: Energy fingerprints of the different joint tissues computed from the virtual monoenergetic images. Attenuation versus energy for the regions of interest shown in the left panel: patella cartilage (blue), soft tissue different from cartilage (red), cortical bone (yellow), and subchondral bone (green). Plot shows mean and standard deviation across subjects for the selected regions of interestBack to article page
