在模拟的基础上，论证了270°高斯脉冲如何用于核磁共振成像实验中的切片选择。结果表明，用具有高斯时域振幅分布的自调焦270°脉冲代替通常使用的选择性90°脉冲，可以省去通常的梯度反转过程，并探讨了这类脉冲的一些特性。©1989学术出版社，Inc。
It is demonstrated, on the grounds of simulations, how 270° Gaussian pulses can be used for slice selection in nuclear magnetic resonance imaging experiments. It is shown that the usual gradient reversal procedure can be omitted if the selective 90° pulse normally used is replaced by a self‐refocusing 270° pulse with a Gaussian timedomain amplitude profile, and some of the properties which are specific to this type of pulse are explored. © 1989 Academic Press, Inc.
