Here we evaluate the excitation homogeneity and SAR of three different Tx arrays after B1 shimming in the human body at 3T. It appears that in this particular comparison an array based on strip line elements can produce better homogeneity and lower SAR than can an array of rectangular loops or an array of mixed elements (strip line and loop). While many factors are considered in designing coils for production, it is hoped that methods and results like these will be used in the future to guide decisions and maximize benefit.
