FIELD: medicine; medical engineering.
SUBSTANCE: method involves determining impedance value applying electromagnetic resonance techniques in frequency bandwidth of 200-500 kHz. Device has oscillator unit, transformer, transducer designed as parallel oscillatory circuit having capacitor and inductance coil and recorder. The transducer inductance coil has additional communication winding one of leads of which is electrically connected to the first metal electrode represented by Kousko mirror. The other lead has the second metal electrode being rounded metal rod. Circuit is connected to the communication winding leads. The circuit has two-position switch and variable resistor.
EFFECT: high accuracy of measurements.
