System and method for obtaining images and spectra of the cavity structure using a 3.0 Tesla magnetic resonance system

摘要

MR system and an interface device and the corresponding intracavity probe. The probe includes a coil loop inside the balloon and the balloon at one end and shaft. Loop has a tuning capacitor and a single drive two capacitors, which are all in series. Junction node between the drive capacitor acts as a ground to balance electrically loop. Tuning capacitors are diametrically opposed on the node may be a loop resonance at the operating frequency of the MR system. Interface, to cut off from the port the loop to the transmission cycle is bound to a port of the MR system the loop on the received cycle of the MR system. When inflating the balloon to be inserted inside the cavity of the subject the probe, MR system may create a spectrum and / or image of the region of interest using an MR signal received by the loop.
