Figure 5

Left panel: Tracing of the NI-LDF Flux signal in response to stepwise increases of the flow in the tube model, provided by increased flow settings on the supplying syringe pump. Right panel: CMBC, TB and the Flux signal of the NI-LDF, plotted against the flow setting of the syringe pump. The response of the Flux parameter is linear, the total backscatter remains constant. The course of the CMBC parameter is similar to the PF4000 response, with a combined value for the offset (noise + Brownian motion) and a stable signal after the onset of the flow of the milk. Note that the scales of the two systems are dependent on instrumental factors (e.g. internal amplification etc.) and are not comparable directly. (CMBC = concentration of moving blood cells, TB = total backscatter.)
