Figure 1. Schematic of DOSI measurement procedure.
(A) demonstrates the grid used with distances between points indicated. The “U” in the center of the grid refers to the subject’s umbilicus. (B) shows a typical scattering spectrum obtained from one subject at point M3, with the mean of three replicate measurements ± SD shown as a line and a shaded area respectively. (C) shows the mean absorption spectrum at the same location in the same subject, also as mean ± SD (D) demonstrates example heat maps of scattering and absorption parameters from one subject over all 30 measurement points with linear interpolation.
