Various methods have been proposed for generation of images by nuclear magnetic resonance (NMR). However, only the variants of the Fourier technique are used on a routine basis in clinical imaging. It is helpful to classify the imaging techniques by the dimension of the region which produces the acquired signal. Then point, line, plane, and volume techaiqnes are discriminated. To optimise sensitivity, it is advantageous to multiplex the space information during data acquisition, so that the acquired signal derives from as many pixels or voxels simultaneously as possible. This chapter reviews concepts of spatial resolution and discusses the less sensitive sensitive-point method and line-scan methods. A reduction of the space dimensions of the NMR signal can be achieved by the use of selective excitation in the presence of field gradients, for instance, by selective pulses. This chapter also considers shaped pulses, composite pulses, pulse sequences, solid-state techniques, magnetisation in field gradients, linear and nonlinear responses.

Keywords:   spatial resolution, nuclear magnetic resonance imaging, sensitive-point method, line-scan methods, selective excitation, shaped pulses, pulse sequences, magnetisation, nonlinear responses, solid-state techniques
