Flip angle

Last revised by Andrew Murphy on 02 Apr 2020

The flip angle is an MRI phenomenon by which the axis of the hydrogen proton shifts from its longitudinal plane (static magnetic field B0) Z axis to its transverse plane XY axis by excitation with the help of radiofrequency (RF) pulses. A RF pulse is sent in at the precise Larmor frequency in relation to the gyromagnetic ratio and magnetic field strength.
