At high fields, B1 inhomogeneity is one of the major challenges that limit imaging performance. Parallel transmission with an array of coils is a recognized solution to B1 inhomogeneity. The self-decoupled coil is attractive in Tx array design since it exhibits intrinsic inter-element isolation that may ease the coil fabrication, and allows the dipole mode as well as loop mode. In this work, we evaluated a series of self-decoupled coils in terms of these parameters and aimed to provide guidance for the practical building of a high-performance self-decoupled Tx array.
