Abstract. A method for diagnosing malignant tumors by analyzing of pulse oscillations recorded with optical photoplethysmographs is proposed. The aim of the work is to create a two-channel pulse sensor that can analyze the correlation of the pulse in different parts of the body. In previous works, a decrease of correlation was found between pulsations of the electrical conductivity of tissues in the area of a malignant tumor and the general pulse. Since the tissue impedance oscillations are caused by the blood flow, it is suggested in our work that photoplethysmography should be used instead of electrical impedance tomography as a more accessible method. The device contains two heart rate sensors that transmit information to a common control card, and software. The pulsometers contain an optical sensor, a system for amplifying and filtering the signal. The software part reads the digitized data and outputs it to the personal computer in real time, calculating their correlation characteristics.

Key words: pulse, impedance, software and hardware complex, signal processing.
