Fig. 4.
Joint spatial–velocity images of xenon Poiseuille flow in a pipe (id = 4 mm, ΔXe = 4.5 mm2/s, Vave = 20 mm/s). The x-axis represents axial velocity (i.e. in z-direction) while the y-axis represents spatial location across the pipe with 0 mm referring to the pipe center. The spectral window in the flow-encoding dimension was kept constant. (A) Computer simulation with Δ = 10 ms. (B) Experiment with Δ = 10 ms. (C) Experiment with Δ = 60 ms. (D) Experiment with Δ = 130 ms. Adapted figure, printed with permission from Kaiser et al. J. Magn. Reson. 2001; 149:145. © 2001 Elsevier.
