A field gradient can be produced in any arbitrary direction by simultaneously
using combinations of all three gradient coils . Another consideration is the
gradient “ rise time " or how much time is required to turn on and establish a

The gradients in the readout ( X ) direction are designed to balance at the center
of the echo ( TE ) , giving no phase encoding at that time . The amplitude of the
phase - encoding gradient selects the Fourier line being acquired .
