Abstract
A diagnostic system using a nuclear magnetic resonance phenomenon comprises an external magnetic field generator, provided externally, for generating a magnetic field in a living body, a thin diameter member capable of being inserted into a body cavity and having flexibility, a high frequency coil, provided at a top end of the thin diameter member, for transmitting and receiving a high frequency, a nuclear magnetic resonance signal measuring device for receiving a nuclear magnetic resonance signal from the living body, and a transformer, provided between the high frequency coil and the nuclear magnetic resonance signal measuring device, for electrically isolating and separating the high frequency coil from the nuclear magnetic resonance signal measuring device in a manner such that the nuclear magnetic resonance signal is transmittable between the high frequency coil and the nuclear magnetic resonance signal measuring device.
