您要查找的是不是：
- When the rf pulse is combined with magnetic field gradients, a spatially encoded signal is produced that can be detected and translated into images. 当射频脉冲与磁场梯度联合起来时，我们可以探测到一个空间编码信号的产生并且将它转变成图像。
- In these nonuniform fields the coil voltage caused by the excitation of an RF pulse rapidly decays to zero, but it can be recovered some time later by applying a second pulse. 在不均匀磁场内，射频脉冲导致的电波很快会消失，但如果隔一段时间后再提供第二次脉冲，又会重新出现。
- For example, when a surface coil is used to transmit a rectangular RF pulse into a uniform water phantom, the amplitude of the B1field can vary by several-fold across the imaged object. 比方说，当一个表面线圈向均匀的水介质发射矩形射频脉冲的时候，B1 场的振幅有可能在成像物体的不同部位发生很大的差异。
