Claims
- 1. A device for adjusting a nuclear magnetic resonance apparatus having an antenna, and an emitting/receiving means comprising:
- a first length of high frequency line connected by one end to said emitting/receiving means:
- an antenna tuning circuit connected to another end of said first length of high frequency line for tuning said antenna and isolated from said emitting/receiving means:
- a second length of high frequency line having a first end coupled to said antenna tuning circuit and having a second end coupled to said antenna.
- 2. A method for adjusting a nuclear magnetic resonance apparatus including an antenna and an emission/reception means, for emitting and/or receiving a radio frequency signal, said antenna being connected by a high frequency line of a given length to said emission/reception means, comprising the steps of:
- inserting between said antenna and said emission/reception means a first portion of said high frequency line length with said first portion being connected by one end, in cascade, to an antenna tuning circuit with said antenna tuning circuit being isolated from said emission/reception means and to a sensor, and by the other end to said antenna, the sensor being itself connected to a circuit for measuring the tuning, with another portion of said line being connected by one end to said emission/reception means and by the other end to said tuning circuit;
- adjusting the apparatus by the tuning circuit as a function of the results delivered by said circuit for measuring the tuning.
