Decoupling technique for transmit coils in NMR spectroscopy and imaging.
A decoupling structure using an additional LC resonant configuration for NMR transmit coils is analysed and the probe sensitivity of the receive coil with the decoupled transmit coil is calculated using simple circuit models. An adjustment-free technique for the decoupling circuit under different loading conditions is proposed using the calculated results and demonstrated by experiments. The proposed method can simplify the probe operation.
