MAGNETIC FIELD COIL, AND MAGNETIC RESONANCE IMAGING DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide an RF coil by which a high-frequency magnetic field having two kinds of magnetic resonant frequencies which have frequencies being close to each other is highly efficiently and evenly irradiated, and which can receive two kinds of magnetic resonant signals which have frequencies being close to each other by a high sensitivity and an even sensitivity distribution, in an MRI device. SOLUTION: A plurality of frequencies which are tuned are adjusted in such a manner that they may become values between resonant frequencies of series resonant circuits which constitute the RF coil.
