摘要：
An intracavity probe for use with a magnetic resonance system includes: a pair of coil loops arranged in a phased array configuration； a pair of decoupling circuits； a pair of output cables； and a spacer material positioned adjacent to an anterior surface of the coil loops. Each coil loop has a drive capacitor and a tuning capacitor. Each decoupling circuit is connected across the tuning capacitor of one of the coil loops. Each output cable is connected at a first end thereof across the drive capacitor of one of the coil loops such that each of the drive capacitors is provided with a separate ground. The spacer material assures a predetermined distance between the pair of coil loops and the region of interest, which thereby reduces intensity of the magnetic resonance signals in proximity to the coil loops, maintains SNR at depth within the region of interest and reduces artifacts.
