Spatial detection in this second dimension will require another method, typically phase-encoding.Frequency Encoding for Slice SelectionFrequency-encoding can also be used to define the position of entire slices in 2D imaging. The basic principle is the same as for within-plane frequency-encoding, ...
Since frequency-encoding seems relatively simple and straightforward, why make things complicated by introducing phase-encoding, parallel imaging, and other confusing concepts? Why not just design gradients so that every voxel has a different frequency and frequency-encode everything?

The high-frequency signal is demodulated by a phase-sensitive lock-in amplifier. The resulting low-frequency output of the lock-in is again demodulated by another phase-sensitive lock-in. As a result, the effective time constant of the system is ∼200 s and the LMR sensitivity increases ...
The FID has undergone accelerated decay due to the action of a dephasing gradientG(x)that is directed along the horizontal axis.G(x)might serve as either a frequency- or phase-encoding gradient. For simplicity we assumeG(x)varies linearly with position(x), having the formG(x)=G•x, ...
