Fig. 6 — Melanin volume fraction estimated from MPM and SFDS data. (a) Melanin volume fraction as function of skin type, corresponding to volar upper arm (circle) and dorsal forearm (asterisk) as determined by MPM. Data represent the average of the melanin volume fraction calculated for five stacks acquired for the same site (volar or dorsal) in each of the 12 patients. The error bars represent standard deviation of the five measurements. (b) Average melanin concentration determined by SFDS. Red (asterisks) are estimates from the dorsal forearm as a function of assessed skin type, black (circles) are estimates from the volar upper arm. The error bars represent an estimated model error from SFDS layered decomposition.
