ABSTRACT:
An ultrasonic wave transmitting/receiving portion transmits ultrasonic waves to a subject via an ultrasonic probe, then receives the ultrasonic waves reflected from the subject via the ultrasonic probe, and then converts the received ultrasonic waves into electric signals. A B-mode DSC portion converts the electric signals received by the ultrasonic wave transmitting/receiving portion into displaying signals. A Doppler signal processing portion detects Doppler signals from the electric signals supplied from the ultrasonic wave transmitting/receiving portion in terms of phase detection and analyzes both blood flow velocity and tissue motion velocity based on the Doppler signals within a processing time assigned to one scanning line. A displaying portion displays concurrently B-mode ultrasonic images supplied from the B-mode DSC portion and information as for blood flow velocity and tissue motion velocity supplied from the Doppler signal processing portion apparently.
