    • A main magnetic field is applied to a target to excite the nuclear spin of a chosen type of atoms in a selected slice of the target. Subsequently, first and second gradient fields, which are parallel to the main magnetic field noted above and the strengths of which vary in the directions of respective first and second crossing axes in the slice, are applied to the target for predetermined period of time. Then, a readout magnetic gradient field, which is parallel to the first gradient field, and the strength of which varies in the direction of the first axis, is applied to the target to detect a free induction signal from the target. The detection of the free induction signal is repeatedly performed with a plurality of different strengths of the first and second gradient fields, whereby NMR data containing chemical shift data is obtained from the slice of the target noted above.
    • 将主磁场施加到靶,以激发所选择的靶的切片中所选类型的原子的核自旋。 随后,平行于上述主磁场的第一梯度场和第二梯度场在预定时间段内被施加到目标上,所述梯度场在切片中的相应的第一和第二交叉轴的方向上变化。 然后,将与第一梯度场平行且其强度沿第一轴方向变化的读出磁梯度场施加到目标,以检测来自目标的自由感应信号。 利用第一和第二梯度场的多个不同的强度重复执行自由感应信号的检测,由此从上述靶标的切片获得含有化学位移数据的NMR数据。
