We proposed an improved method for Maxwell compensation
which compensates slice gradient (Gx) and readout gradient (Gy) mutually.
This method has 3 benefits compared to traditional methods: (1) Special
attention is paid on minimizing the ESP prolonging. (2) The gradients are
derated as much as possible without prolonging the ESP, which helps to reduce
the cross axis Maxwell term and eddy current. (3) Mutual compensation makes
the Maxwell compensation for FSE with flow compensation more effective.
