摘要
An MR system features an intracavity probe and associated interface device. The probe includes a shaft, a balloon (60) at one end thereof, and a coil loop (2) within the balloon. The loop has two drive capacitors (21, 23) and a tuning capacitor (24), all of which in series. A junction node (22) between the drive capacitors serves as a ground for electrically balancing the loop. Diametrically opposite the node, the tunding capacitor enables the loop to resonate at the operating frequency of the MR system. The interface (100) allows the MR system to couple the loop to a port of the MR system during a receive cycle thereof and decouple it from the port during a transmit cycle thereof. With its balloon inserted and inflated within a cavity of a patient, the probe allows the MR system to generate images and/or spectra of the region of interest using the MR signals received by the loop.
