An Improved Maxwell Term Compensation Method for FSE Images

Weiwei Zhang¹, Yongchuan Lai¹, Xiaocheng Wei¹

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.
