While neighboring coil elements can be decoupled by various means, it is more difficult to mitigate the often substantial coupling to next nearest neighbors. This is particularly problematic with transmit arrays, since preamp decoupling cannot be used to control next nearest neighbor coupling. We present a novel array design with triangular elements which allows capacitive decoupling between neighboring coils and inductive decoupling between next nearest neighbor coils. The triangular elements also present diverse B1 profiles, allowing for acceleration along the Z direction.
