摘要:
The present invention is a method by which diodes are connecting in a circuit such that they are more robust. The method involves placing two diodes of opposite directions in parallel and applying a DC bias such that a forward diode may then handle higher than normal voltages and a reverse diode provides a failsafe in the event of a reverse bias.

The present invention is a dual resonant breast coil design for combined sodium and proton breast MRI with increased SNR at 3T when compared to a coil with a single proton and sodium channel. The coil consists of a 7-channel sodium receive phased array, a large sodium transmit coil, and a 4-channel hydrogen transceive array. An interleaved overlapping coil layout is used to reduce coupling between sodium and proton coil elements. The new composite array coil demonstrates a 2-5× improvement in SNR for sodium imaging when compared to a simple single-loop dual resonant design.
