Fig. 15.

(a) The $g_1(\tau )$, measured by the proposed MVIM algorithm using the camera based system, is compared with SCOS fitted $g_1(\tau )$ for human hand blood cuff experiment during pre-cuff, cuff and post cuff phases. The shift in $g_1(\tau )$ curve towards right indicating the decrease in blood flow. (b) Relative blood flow (rBF) for the five volunteers for pre-cuff, cuff and post cuff phases. It can be seen that there is almost $70-80\mathrm{\%}$ decrease in blood flow between pre-cuff and cuff phases. Here the superscript M and S in the legend indicates that it is MVIM recovered and SCOS fitted $g_1(\tau )$ respectively.
