Today the special attention is given to noninvasive diagnostic methods of cardiovascular system. It is associated with growth of number of cardiovascular system diseases including cerebral vessels. This paper is described rheoencephalographic (REG) method that allows to estimate circulatory system and this is actual with cerebral disturbance diagnostics, strokes, tumors and various craniocerebral injury. REG-method characterizes the hemodynamic parameters estimation of the three main paired brain arteries: internal and external carotid arteries and vertebral artery. The analysis of REG-signals by using our software included determination of systolic wave amplitude, value of basic impedance and predominant type of REG-cycle construction in 10-minute interval. Arabic numeral is the predominant types of REG-cycles in 10 cardiocycles interval. The use of 6 types REG-classification gives more detailed estimation of cerebral parameters than the well-known classifications of rheographic signals. The analysis of 6 types REG-classification is shown expediency of its use in clinical practice such as complementary of common classifications. Multi-channel REG researches have shown that effect in area of a bioadequate electromagnetic field is bounded only by region of vascular bed pathology and during carrying out ones on a brain.
