Figure 6 Multiple spins precessing with the Larmor frequency around the direction of B0 (left).
After a 90° radio frequency (RF) pulse, the spin population of the energy levels become equal and the spins precess coherently (middle). The magnetization vector M0, rotates into the transverse (x-y) plane (right).
