Synopsis

This lecture will cover the basic concepts needed to understand the theory and implementation of multi-dimensional RF pulses. The ideas of excitation k-space and the Fourier picture for small tip angle RF pulses will be covered in detail. The common k-space trajectories and pulse designs will be discussed. Examples of 2D and 3D spatially selective excitations as well as spectral spatial pulse designs will be presented. Applications including field inhomogeneity compensation and parallel transmission will be covered as well.
