1. A magnetic resonance imaging (MRI) apparatus comprising: an MRI system having a plurality of gradient coils positioned about a bore of a magnet and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images; and a computer programmed to: calculate a cost for each point to be acquired in k-space; acquire MR data based on the calculated cost for each point; and generate an MR image using the acquired MR data.
