We present a new design of a radiofrequency resonator for urological applications. The resonator functions by inductively coupling to the body coil of a 1.5 T MR-scanner. This configuration of the Tx-Rx path allows increasing the transmission efficiency and signal to noise ratio (SNR) while reducing the specific absorption rate (SAR). Phantom and in-vivo imaging shows that the resonator provides around 100-fold SAR reduction and 10-fold transmission efficiency increase. Phantom imaging shows doubled SNR compared to the commercial flexible 4-element Rx coil. In-vivo imaging shows only a 50% increase in SNR, improved patient positioning and reduced the artifacts rate.
