Stacked histogram of scaled intensity for the voxels segmented as bone and background for one of the bone specimens. For multislice computed tomography using photon-counting detectors (PCD-CT) and multislice computed tomography using energy-integrating detectors (EID-CT) data, the segmentation was achieved by the automated region growing algorithm, while the micro-CT data was segmented using Otsu thresholding. For the PCD-CT, the combination of a field of view of 51 mm and a matrix of 1,024 × 1,024 was chosen and for the EID-CT the mAs setting with the same CTDIvol as the PCD-CT was used.
