Fig. 6:

A) Normalized ln (V · r) vs r for a single set of phantoms doped with 0%, 5% and 10% Intralipid, 0.144% Naphthol Green B and 31.4% BSA. B) The effect of Intralipid and BSA concentration on $u_s^{\prime }$ before and after coagulation measured in 3 sets of phantoms. By interpolation, the requisite concetraion of Intralipid was found to be 8.06%. Error bars represent one standard deviation and are not visible at all points.
