Abstract
A local coil for magnetic resonance imaging of the breast employs two generally cylindrical coils isolated from each other by a radio frequency shield. The coils comprise multiple loops displaced along the axis of the cylinder and connected in parallel to provide uniform coverage of the volume. Coils may be activated individually or at the same time with their signals combined. In the former case, the non-activated coil is actively decoupled by stimulating its decoupling circuit network with a DC bias signal from the system. The activated coil decouples passively during transmit.
