METHOD AND DEVICE FOR DIAGNOSING ORGANISM STATE USING ULTRAHIGH FREQUENCY RADIATION OF NON-HEATING POWER LEVEL Russian patent published in 2004 - IPC

FIELD: medicine; medical engineering. SUBSTANCE: method involves sending ultrahigh frequency signal controllable by frequency. The signal is defined by minimum power level detectable by receiving tract. Amplitude-frequency characteristics of transition coefficients of point pairs under study are recorded by means of digital logical unit. Measurement results are statistically processed and compared to reference results obtained from healthy people group. Measurement result deviations from the reference values are used as diagnostic values. An additional unit for controlling ultrahigh frequency signal is introduced between ultrahigh frequency oscillator having electronic frequency tuning means and transmitting antenna. Negative feedback circuit is also introduced into the design. The circuit has low frequency amplifier output and low frequency input of electronic unit for controlling ultrahigh frequency signal power. The control voltage generator is connected to the digital logical unit output via digital-to-analog converter. Each of the receiving and transmitting antennas is designed as two- wired coaxial transmission line having grounded conductors electrically connected to each other in a way that length of circuit built as a result of this connection between the antenna ends contacting skin cover is not greater than 3/4 of minimum operation bandwidth wavelength. EFFECT: lower diagnostic signal power level. 17 cl, 9 dwg
