摘要：
FIELD: medicine.SUBSTANCE: invention refers to medical equipment, namely devices for detecting females breast new growths. The method consists in the fact that four metal electrodes regularly spaced on a rigid dielectric base plate around the circumference, the length of which does not exceed a breast circumference, at a pre-set height from the breast base, are applied to the breast. A basic cycle of measurements is performed by passing the measurement current twice through a pair of the polar opposite current electrodes with neutralising each of these electrodes in turn, and measuring at the same time a potential different of the potential electrodes arranged along the line orthogonal with the mounting line of the current electrodes the measured potential different is stored as relevant to two quadrants of a breast projection on a chest plant, adjoining the neutralised current electrode. The two potential differences derives are compared in absolute magnitude if a difference of their absolute values exceeds a pre-set threshold, the patient appears to be diagnosed with a breast new growth the two quadrants having a greater absolute measured potential difference are considered as a new growth localisation. An electrical impedance mammography device comprises a replaceable electrode unit in the form of a dielectric hemisphere, an inner surface of which bears at least four equally spaced flat metal electrodes around the circumference each of the electrodes is provided with a separate electrical lead they are divided in at least two groups, each of which is formed by two polar opposite electrodes and connected to a controlled multiplexer-demultiplexer of an electronic unit built in a handle. The multiplexer-demultiplexer is connected through a voltage meter and analogue-to-digital converter to a microprocessor connected to an indicator unit, and to a controlled measurement current generator.EFFECT: using the invention enables to extend the range of devices for detecting
