Indicator dilution curves (IDCs) fitted by LDRW double fit method and impulse response method. These IDCs were constructed from post-processing imaging analysis at the level of inflow and outflow tubes at a flow of 2 L/min and true volume of 718 mL. The dotted black line is the IDC at the level of the inflow tube and outflow tube. In the upper picture, the red and blue lines depict the IDCs by the double fit method according to the LDRW model of the inflow and outflow tube. The vertical dashed lines represent the MTTs of each curve. In the bottom picture, the green line depicts the IDC according to the LDRW model impulse response method.
