Description
technical field [0001] The invention relates to a nuclear magnetic resonance instrument, in particular to a magnetic resonance probe vector tuning detection device and method. Background technique [0002] The nuclear magnetic resonance instrument is developed and produced by applying the principle of nuclear magnetic resonance. It excites the resonance phenomenon of the atomic nucleus of the measured object by transmitting high-power radio frequency pulse signals to the measured object. The probe is the transmitting part of the radio frequency pulse and the receiving part of the nuclear resonance signal under test, and its performance directly affects the efficiency of radio frequency excitation and the sensitivity of the magnetic resonance signal. In order to efficiently emit radio frequency pulses to excite the resonance phenomenon of atomic nuclei, the resonance frequency of the radio frequency coil of the probe should be the same as the frequency of the emitted radio fr...
