1. A magnetic resonance (MR) imaging apparatus comprising: a plurality of gradient coils positioned about a bore of a magnet; an RF transceiver system and an RF switch controlled by a pulse module to transmit RF pulses to an RF coil assembly and receive MR signals therefrom; and a controller programmed to: cause acquisition of a series of scout images; determine a non-linear motion of an anatomy of interest among the series of scout images; and adjust a position of an acquisition slice during MR image acquisition based on the non-linear motion of the anatomy of interest.
