ABSTRACT:
The invention relates to a Doppler velocimeter comprising a transmitter composed of a plurality of independent transducers for generating beams of ultrasonic energy, an ultrasonic generator for generating a plurality of noise signals, each noise signal being independent of the other, and a receiver for receiving beams of ultrasonic energy reflected from a target. Each noise signal is applied to several of the plurality of transducers and maintained separately upon generation of the beams of ultrasonic energy. Received ultrasonic energy is processed through the use of groups of dual correlators, further processed and displayed. The invention finds an application in the real-time display of blood flow velocities in a segment of blood vessel.
