FIG. 7.
Speckle analysis method to measure erythrocyte aggregation. (a) Temporal variations of the average speckle area (ASpeckle) at Ht = 40% with respect to dextran concentration (CDextran). (b) Quantitative evaluations of the characteristic time (λSpeckle) and A0 obtained by Eq. (7) according to CDextran. Data points (CDextran = 0.03%) and its fitting curve are included. Each data set indicates the mean value and standard deviation evaluated from three test samples.
