Fig. 8From: Quantitative determination of the lowest density domain in major fault zones via medical X-ray computed tomographyX-ray CT image analysis results for the Oritodani outcrop samples. CT images of samples a T-3, b K-1, and c T-5. CT number histograms for d T-3-1, e T-3-3, f T-3-4, g K-1, and h T-5. The NCTM value in each zone was calculated near the center (within the white dotted lines in (a)–(c)), with the peripheral values excluded. CT number profiles for i T-3, j K-1, and k T-5, with the values calculated along the dash-dotted lines in (a)–(c), respectivelyBack to article page
