METHOD FOR PRODUCING MULTI-SLICE NMR IMAGES

In an NMR imaging system spins in a set of slices are simultaneously excited by a composited 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 k.sub.y -dependent phase factor. The k.sub.y -dependent phase factor causes the iamge of each slice to be offset in the resulting reconstruction so that each slice image can be separated from the others.
