A technique using a multi echo sequence. A slice selective RF pulse is applied in conjunction with a X magnetic field gradient. This excites spins in a YZ plane. A 180° slice selective RF pulse is applied in conjunction with a Y magnetic field gradient. This rotates spins located in a XZ plane. A second 180° slice selective RF pulse is applied in conjunction with a Z magnetic field gradient. The second 180° pulse excites spins in a XY plane. The second echo is recorded as the signal. This echo represents the signal from those spins in the intersection of the three planes. Fourier transforming the echo produces a NMR spectrum of the spins located at the intersection of the three planes. By prudent choice of the X, Y, and Z gradients the signal voxel can be positioned anywhere in the imaged object.
