Fig. 3.4.2 Schematic description of the three-dimensional SPRITE imaging technique. Gz, Gx and Gy are the phase encode magnetic field gradients and are amplitude cycled. A single data point is acquired at a fixed encoding time tp after the rf excitation pulse from the free induction decay (FID). TR is the time between rf pulses. Notice that Gx is ramped (+GZ max to -GXt max) and one /c-space point is acquired for each value of the magnetic field gradient. Gy and Gz are on during the Gx magnetic field gradient ramp and turned off at the end.
