Specific Absorption Rate (SAR) and B1 inhomoeneity are two main problems of high field Magnetic Resonance Imaging. Multi-channel transmit systems may be used to fight againts inhomogeneity problems. Variable Rate Selective Excitation (VERSE) is an useful method to deal with SAR problems. Application of VERSE method to multi-channel transmit system gives chance to design SAR efficient RF pulses with minimum B1 inhomogeneity. To obtain maximum SAR reduction with VERSE method RF pulse design should be optimized.
