Abstract
Phased array systems using ultrasound waves have been widely used to produce cross-sectional images of the heart in recent years. Ultrasonic Doppler techniques also supply useful diagnostic information on blood flow in living organs. In the Doppler technique, continuous wave Doppler (CWD) is used to measure high blood flow velocity quantitatively, and it is very desirable that this CWD function be implemented in phased array systems. There has been some commercial equipment in which the CWD is available, however, it lacked measurement sensitivity.
