Measurement of the RBC flow. (a) Two-dimensional image of cortical vasculature labeled with FITC, with the white arrow marking the line scan position. The scale bar is 50 μm. (b) The intensity plot of 1000 line scans taken along the axis of the blood vessel during 1.49 s. The length of the individual line scan is 18.69 μm. The estimated RBC velocity is 0.6 mm/s.
