Endoscope apparatus
First Claim
1. An NMR metering endoscope apparatus comprising:
- an endoscope having an elongate insertable part having a tip part insertable into a body and including an observing window and an illuminating window formed in the tip part, an observing means having a visual field for observing an object to be imaged by receiving light from the object entering through said observing window, an illuminating light output means for emitting an illuminating light through said illuminating window and a hollow channel formed within said insertable part including an opening in said tip part; and
an NMR (nuclear magnetic resonance) metering probe having a signal transmitting member insertable into said body through said channel and opening, said probe being connected at one end to an NMR metering apparatus so as to transmit high frequency signals therefrom, and a loop-like antenna connected to the other end of said signal transmitting member to receive said high frequency signals, said loop-like antenna being projected out of the opening of said channel formed in said tip part to radiate said high frequency signals and generate a high frequency magnetic field such that a high frequency magnetic field is delivered to a body part by said antenna so as to cause NMR radiation from said body part, said NMR radiation being received by said antenna and delivered to said NMR metering apparatus to enable detection of a physiological variation in the body part, whereby location of the source of the radiation within said body can be visually identified by use of said observing means of said endoscope.

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.
