Abstract
This endoscope apparatus adapted to meter NMR (nuclear magnetic resonance) is provided with an endoscope having a channel and an NMR metering probe insertable through the channel. The endoscope has an elongate insertable part having an observing window and illuminating window in the tip part, an observing system for observing an object to be imaged by receiving a light from the object entering through the observing window, an illuminating light output system emitting an illuminating light through the illuminating window and a hollow channel formed within the insertable part and opening in the tip part. Preferably, at least the tip side of the insertable part if formed of a non-ferromagnetic characteristic material. The NMR metering probe has a signal transmitting member insertable through the channel of the endoscope, connected at one end to the NMR metering apparatus and able to transmit high frequency signals and a loop-like antenna part connected to the other end of the signal transmitting member and projected out of the opening of the channel.
