4837516 Tuning device for nuclear magnetic resonance imaging apparatus and nuclear magnetic resonance imaging apparatus including the tuning device

Ryoichi Takahashi

A tuning device for an NMR imaging apparatus capable of functioning responsively and accurately in the presence of a strong magnetic field. The device includes LC circuit formed by coils and tuners including variable capacitors, and ultrasonic motors which tunes the LC circuits to a resonant frequency by adjusting the variable capacitors. An NMR imaging apparatus including this tuning device is also disclosed.
