- 摘要：
PROBLEM TO BE SOLVED: To provide an RF coil capable of changing the distance and angle between two coils and sufficiently removing magnetic coupling by a method of generating capacitive coupling using a capacitor, and an MRI apparatus using the RF coil.
SOLUTION: When the distance or angle of the coil 41 and the coil 42 changes and mutual inductance M between the coil 41 and the coil 42 changes, by changing the variable capacity Cm of a neutralizing capacitor 46 and a neutralizing capacitor 47, the magnetic coupling by the mutual inductance M between the coil 41 and the coil 42 is removed.
