Title :
Parameters of frequency-dependent dipole polarization at human stomach healthy and tumoral biotissues definition
Abstract :
In the paper the outcomes of the human stomach healthy and tumoral biotissues coefficients of polarization massifs researches describing parameters of dipole polarization and allowing to distinguish these biotissues are submitted. The advantages of a multifrequency method of biological tissues electrical impedance research having for an object diagnosing of their anatomic and physiological change in comparison with a healthy biotissue are described. The parameters of dipole polarization determining an anatomic and physiological condition of a biotissue are certain. On the basis of aplenty human stomach healthy and tumoral biotissues electrical impedance measurements character of dipole polarization for each of them is defined, that together with the conducted histological researches has allowed to determine correspondence of these biotissues electrical parameters to their anatomic type.
