In an NMR imaging system spins in a set of slices are simultaneously excited by a composite RF excitation pulse in each NMR pulse sequence of a scan. The composite RF excitation pulse contains a set of terms, each of which excites a separate slice and each of which is modulated by a ky-dependent pha...

Zusammenfassung:In an NMR imaging system spins in a set of slices are simultaneously excited by a composite RF excitation pulse in each NMR pulse sequence of a scan. The composite RF excitation pulse contains a set of terms, each of which excites a separate slice and each of which is modulated by a ky-dependent phase factor. The ky-dependent phase factor causes the image of each slice to be offset in the resulting reconstruction so that each slice image can be separated from the others.
