[Improvement of the information value of multifrequency impedancometry for detection of small tumor arrays].
Use of multifrequency impedancometry makes it possible to considerably increase the information value of electroimpedancometry for malignant tumor diagnosis. Integral characteristics of the tissue electrical impedance vs. frequency curves Z(f) in normal and pathological states are used to obtain additional diagnostic information about the type and physiological state of biological tissues on the basis of calculation of quotients K(P). The number of these quotients depends on the number of diagnostically significant frequencies and integral characteristics Z(S). Ratios of quotients K(P) for the same frequency domains and ratios (and differences) of areas under the curves Z(f) for normal and pathological biological tissues can be used as diagnostically significant correlation parameters.
