Fig. 6From: Virtual monoenergetic images from photon-counting spectral computed tomography to assess knee osteoarthritisSynchrotron radiation images at 55 keV, PCSCT monoenergetic images at 60 keV and HR-pQCT images for 2 samples: a normal one (specimen 4); and an osteoarthritic one (specimen 7). The cartilage border with joint space is visible on the monoenergetic images based on synchrotron radiation, taken as references and the virtual PCSCT monoenergetic images. The yellow arrows correspond to cartilage defectsBack to article page
