Method and apparatus for intracorporeal medical imaging using self-tuned coils |
摘要 |
Disclosed herein is an RF probe for use with a medical imaging apparatus, the probe comprising an intracorporeal self-tuned resonator coil for receiving a signal indicative of an image of an interior portion of a body. The resonator coil is preferably self-tuned to a desired frequency according to one of its geometric parameters. According to one embodiment, the resonator coil comprises a base coil having a plurality of turns and an antenna in circuit with the base coil and extending axially outward therefrom, the antenna having a length such that the resonator coil is self-tuned to a desired frequency. The antenna is preferably a monopole. The resonator coil is also preferably self-matching with respect to a transmission medium coupled thereto. Because the preferred resonator coil of the present invention is self-tuning and self-matching, it avoids the use of bulky and relatively expensive tuning and matching circuits.
