Abstract
A receive coil for MRI includes a stacked pair of coil elements to communicate the respective MR signals therein to the signal processing system in separate channels. This greatly increases image SNR and penetration depth and in parallel imaging. The coils are arranged in a stacked relationship so as to be at least partly and preferably wholly overlapped and lying in the same or closely adjacent planes. The coils include tuning capacitors to a common resonant frequency. The coils are connected by a conductor arranged such that the signals of the first and second coils are decoupled. The conductor can form a common portion of the coils including a capacitance of in the common portion arranged. The coils can be connected by two conductors one of which is a short and the other contains a capacitor. In both cases the connection conductors provide the decoupling.
