Simulated inversion efficiency for laminar flow in a vessel as a function of (a) the ratio Gmax/Gave. A constant maximum vessel velocity of 40.3 cm/s is assumed; (b) time gap between two RF pulses (Δt). A constant maximum vessel velocity of 40.3 cm/s was assumed, and the maximum gradient of 9 mT/m was used; (c) maximum velocity for control and label strategy in contrast with combined efficiency. A maximum gradient of 9 mT/m was used; (d) maximum velocity (cm/s) for different T2 blood relaxation times: T2 = 0.25 s; T2 = 0.10 s while keeping T1 as a constant 1.55 s; There is no noticeable efficiency difference between T1 = 1.55 s and T1 = 1.3 s for fixed T2 of 0.25s. An average RF amplitude and gradient of 1.7 μT and 1 mT/m were used in the above simulations.
