Figure 2. The residue function curve R(t) obtained from deconvolved time-concentration-curve. Mean transit time (MTT) and time-to-maximum (Tmax) parameters are directly measured from the curve. CBF (cerebral blood flow) and CBV (cerebral blood volume) are calculated from the time point of the curve.
