Abstract
Two components of the velocity of blood or similar liquids and the true flow vector are derived by a linear transducer array cross-beam configuration. Ultrasound pulses are transmitted from the center elements and backscattered echoes are received by left and right receiver sub-arrays whose locations depend on the observation point. A duplex imaging system with a sector scanner incorporates a Doppler modality with little added complexity and provides components of flow velocity parallel to and transverse to the acoustic beam direction from which the true velocity vector is computed.
