A novel method for SAR reduction for slice- or slab-selective excitation is proposed which uses an array of two linear phase RF coils and two channel transmission to reduce SAR with no change in pulse length, bandwidth, or slice profile compared to conventional excitation. FDTD simulation results show a reduction of SAR by a factor of two.
