Abstract This article is devoted to the study of possibility detecting breast tumors, which can be used for early diagnostics cancer, by dielectric impedance spectroscopy method. Dielectric a version bioimpedance method, based on concept tissue as heterogeneous dielectric, electrical and mathematical models are Havriliak-Negami model. opens getting rid direct mechanical contacts between sensors mammograph skin. To determine sensitivity (DIS) series experiments was performed with phantoms without inclusion physiological solution (isotonic saline solution) agar-agar. Using special capacitive sensor an LCR meter, frequency response determined. Analysis statistical characteristics differences in curves showed significant (up 8% active R 4% reactive X components). The results confirmed operability An important direction further research most informative range.
