ABSTRACT

The algorithms of processing data array for electric impedance tomography are proposed. The ways of developing medical diagnostic complexes that involve electric impedance diagnosis and electric stimulation in a patient are shown. The adaptive chains of coordination of impedances have been studied on mathematical models and in experiments. These chains make it possible to fix high-frequency power during electrostimulation and to measure the complex impedance of objects.

ABSTRACT

Problems in the construction of automatically changes-adaptable generators made by using planar technology are considered. Adaptation methods realizing their devices are proposed. Experimental findings are presented. There is a decrease in the reflected power from a variable within 6 octaves of a load by 30 dB.
