Abstract
A method is provided for substantially simultaneously manipulating spins in a plurality of slice locations using a magnetic resonance imaging ('MRI') system that includes a radio frequency ('RF') coil array composed of a plurality of RF coil elements, and in which power deposition, which may be measured as specific absorption rate (“SAR”), is reduce A plurality of slice locations to be substantially simultaneously manipulated with the MRI system are selected, and an RF transmission map (Bmap) is provided for each of the plurality of RF coil elements. A subset of slice locations to be manipulated by each of the RF coil elements is then selected using the provided RF transmission maps. Using the selected subsets of slice locations, an RF pulse to be transmitted by each of the RF coil elements is designed. The designed RF pulses are then substantially simultaneously transmitted by the MRI system to substantially simultaneously manipulate spins in each o the plurality of slice locations.
