An apparatus for measuring Carotid Arteries movement without physically connecting electrodes or other sensors to the body was developed. The measurement system was implemented to simultaneously monitor the Carotid Arteries and ECG in order to get move valid information for detection and diagnosis of cardiovascular disease. The designed apparatus is based on Doppler radar with frequency of 2.4GHz and at the distance of up to 3 cm will be capable of detecting the vibrations of the Carotid Arteries, without any contact with the personís body. In this paper we present the theory, and preliminary results of our basic Carotid Arteries monitoring setup.
