Long multidimensionally selective RF pulses suffer from main field offresonances and from relaxation taking place during the RF transmission. Parallel transmit techniques can reduce these problems by shortening the total duration of the pulses. In addition, algorithms that account for offresonances in the pulse design have been demonstrated. In this work a parallel transmit RF design method is presented for creating pulses that are inherently compensated for transverse relaxation (T2*). The presented algorithm can be understood as a generalization of existing offresonance correction schemes into the complex domain.
