| 摘要 |
The present invention is directed to a system and method for harmonic excitation of magnetic resonance (MR) signal for interventional MR imaging (MRI). The system includes an implantable RF coil that excites MR signals in the subject, when driven by lower frequency RF filed from an external coil. This approach permits detection of MR signal in close proximity of the inserted coil by a standard MRI receiver coil without background from the rest of the subject. The procedure allows precise determination of a position of the inserted coil, within the subject. The procedure also allows obtaining localized MR images and spectra. |
