Figure 1:

The net phase change of a series of isochromats in a single voxel. a. The phase evolution during a balanced readout. b. The phase evolution produced by the spoiler gradient along the slice direction. The faded rainbows indicate phase evolutions without motion, while the bright rainbows show the motion corrupted phase evolutions. Delta ɸ indicates the phase difference between the first refocused coherence pathway and the magnetization that will be freshly excited by subsequent excitations.
