Abstract

It is a big challenge to produce as homogeneous as possible B0 static magnetic field. Susceptibility differences between the tissue and air introduce inhomogeneities especially pronounced at high fields. Recently proposed close fitting array of circular loops provide improvement in B0 shimming. Based on the same concept, we proposed coil elements with irregular shape. The shape of the coils was designed by using of genetic algorithm. Theoretical investigation showed that performance of the 16 channel array of irregular elements was comparable or better than 48 channel array consisting loop elements.
