FIELD: medicine.
SUBSTANCE: method involves placing object under measurement into sensitive inductive NMR-analyzer element, displaying measurement results as NMR-signals and comparing them to calibrating measurements. Patient finger is placed into the sensitive inductive NMR-analyzer element manufactured as transducer coil arranged in inhomogeneous magnetic field, the field is modulated in frequency using acoustic frequency oscillator and magnetic field modulation coils in permanent magnetic field in a way that magnetic field inhomogeneity satisfies the following conditions: 2*104≤δH0≤10-1, H0≠Hp, Hp=f/γ, where δH0 is the magnetic field inhomogeneity, H0 is the permanent magnetic field intensity, f is the high frequency oscillator frequency, γ is the gyromagnetic ratio, Hp is the resonant magnetic field intensity, inhomogeneous magnetic field intensity being measured by sending rectangular current pulse to the coils for producing magnetic field pulse. Nuclear magnetic resonance state being achieved, high frequency field is modulated in amplitude. The signal coming from high frequency oscillator circuit is transformed as a low frequency alternating current signal into NMR-signal. Measurement results are obtained as exponent value determining relaxation time T1.
EFFECT: high accuracy and reliability of measurements.
