Summary
[edit]| Description | Video schematically showing the behavior of spins in a spin echo sequence: notice the disruption of the magnetization due to dephasing and its restoration after the inversion pulse. The reference system is assumed to be the "rotating frame", where only the delta rotation with respect to the Larmor precession due to the main magnetic field is shown, which explains the rotation of the spins in the opposite direction after the inversion. |
