Figure 3

Selecting the region of interest for the aorta, using the peak contrast concentration in the population blood (a) or the individual blood concentration (b) and for the segmental arteries (c). Each is accompanied by its mean concentration time curves (solid line; squares indicate data points) and arterial input functions (solid line alone), fitted using a mixture between a Gaussian function and an exponential function modulated by a sigmoid function.
