ABSTRACT:
In a magnetic resonance tomography apparatus and a method for the operation thereof, two neighboring slices of an examination subject are simultaneously excited and the measurement time thus can be shortened without SNR loss. The radiofrequency excitation pulse encodes the first slice with a phase offset of +90° or −90° compared to the second slice, so that a response signal contains magnetization information about both slices, [this information] being separated on the basis of the phase offset.
