Multi-Slice Two- And Four-Fold Acceleration with Single- And Eight-Channel Coils, Respectively

Andrzej Jesmanowicz¹, Shi-Jiang Li¹, James S. Hyde¹

Complex-valued tailored pulses have been used in an EPI sequence to excite two or more slices in human brain using a whole-brain transmit coil. One or more members of a receive-coil array have been used to acquire multi-channel image data. Complex-valued coil profiles have been used to recover slices, and parallel image formation has been demonstrated. Acceleration by a factor of 4 has been achieved with an eight-channel head coil.
