The calf of a healthy male subject imaged at ${\rho }_{10}$ and ${\rho }_{20}$. (a) Photograph of the $5\mathrm{cm}\times 7\mathrm{cm}$ imaging area (dotted box). Ultrasound at the center of the imaged area measured a skin-adipose layer of 4.8 mm. (b) THbMb of the imaged area at ${\rho }_{10}$ with an average value of $110.4\pm 14.3\mu \mathrm{M}$ (c) THbMb of the imaged area at ${\rho }_{20}$ with an average value of $126.8\pm 12.4\mu \mathrm{M}$. (d) The mean and standard deviation of THbMb for ${\rho }_{10}$ and ${\rho }_{20}$. The rank sum test supports that the THbMb distributions were different ($p<0.001$). (e) ${\mu }_s\mathrm{n}$ of the imaged area at ${\rho }_{10}$ with an average value of $0.63\pm 0.05{\mathrm{mm}}^{-1}$; (f) ${\mu }_s\mathrm{n}$ of the imaged area at ${\rho }_{10}$ with an average value of $0.48\pm 0.03{\mathrm{mm}}^{-1}$. (g) The mean and standard deviation of ${{\mu }_s}^{\prime }$ for ${\rho }_{10}$ and ${\rho }_{20}$. The rank sum test supports that the ${{\mu }_s}^{\prime }$ distributions were different ($p<0.001$).
