Figure 1From: Tissue phase mapping using breath-hold 4D PCMRExample data from a healthy volunteer. Top; peak S wave, bottom; peak E wave. a) 2D vector plots from the mid slice, b) Longitudinal velocity, c) Radial velocity, d) Tangential velocity. The colors represent the velocities, with reds representing shortening/contraction/clockwise rotation, and blues representing lengthening/expansion/counter-clockwise rotation.Back to article page
