(a) Mass density measured at each step. The averaged value was estimated from the region of interest of 20 × 20 pixels on the sectional image. The error bars show the standard deviation. (b) Histograms of mass density measured at the left part of the sectional images shown in Figs. 6(a) and 6(f). (c) Histogram of mass density measured at the sectional image of formalin-fixed aorta. |
