MRI 4-DISTURBANCE OF THE EQUILIBRIUM

1. Applying an oscillating, transverse magnetic field will cause the nuclear magnetization, which is aligned in the equilibrium position along the magnetic field to precess at some angle.

2. The most favoured angle is 90 o .

3. This is done by applying the oscillating field for just the right amount of time.
