(57) Abstract :
The invention proposes to equip the tip of a surgical instrument such as a needle or catheter or any other instrument with an
ultrasound transducer array to measure flow just in front of the tip by means of time and frequency differences between the sent
and received pulses. Since no image is required only a few transducer elements are required. The transducer elements generate a
pressure pulses in specific directions and receives its echos without the use of imaging techniques and complex driving
electronics. Using the frequency shift and time delay of the received signals the proximity and lateral direction of the blood flow
may be detected thus identifying blood vessels.
