Abstract
In magnetic resonance imaging apparatus having a resistive electromagnet with a bore 6, r.f. excitation pulse substantially simultaneously excites a number of slices A to D which are phase encoded and frequency encoded in the usual way, the direction of the main field being along the bore of the electromagnet in the direction z. The receive coil consists of an array of coils 5a to 5d which view different spatial regions of the imaging volume and the outputs of which are combined in different ways in order to reduce the number of slice encoding steps in the z-direction needed to distinguish between the slices A to D. Each coil of the array 5a etc. can form part of a two dimensional array in order to reduce the number of phase encoding steps in the phase encode direction.
