Method We searched for an optimal parameter vector x = [α1 α2 α3 φ2 φ3 τ2 τ3], where αn are flip angles and φn the phase for the n RF pulse (intervals of 1°), and τn= TRn/TR1, with the range 0.05≤ τ ≤ 1.1 at intervals of 0.01 (Fig. 1). The SA algorithm used is described in [5]. The step adjustment of each parameter was adapted after every 20 iterations to maintain, as far as possible, a 1:1 rat...
