(a) Three orthogonal views in a 3-D volume of in-vivo normal nail-fold skin (left-up: cross-section in an $x\text{-}z$ plane of $2\times 0.6\mathrm{mm}$, right-up: cross-section in a $y\text{-}z$ plane of 1 mm by 0.6 mm, left-bottom: en face image in an $x\text{-}y$ plane of $2\times 1\mathrm{mm}$, and right-bottom: schematic of nail-fold with a red-line box that indicates the imaged area); (b), (c), and (d) are the en face images at the corresponding depth indicated with the red arrows in the left-up image of Fig. 1(a), respectively; (e) a volume rendered 3-D movie of the nail-fold imaged (Video 1, MOV, 803KB) [URL: http://dx.doi.org/10.1117/1.JBO.17.12.126006.1].
