ABSTRACT:
In an imaging apparatus using the nuclear magnetic resonance, a solenoid coil and a slot-resonator coil are combined with each other so as to constitute a quadrature-phase detection probe. In order to operate the slot-resonator coil at low frequency, inductance is added to the slot-resonator coil. Further in order to cut the coupling between a transmitting coil and a receiving coil in a cross coil system, a capacitor together with the added inductance to form a resonant circuit is connected in parallel to the inductance. A favorable probe can be obtained in a vertical-magnetic field type imaging apparatus.
