摘要

A hand held ultrasonic instrument is provided in a portable unit which performs both B mode and Doppler imaging. The instrument includes a transducer array mounted in a hand-held enclosure, with an integrated circuit transceiver connected to the elements of the array for the reception of echo signals. A digital beamformer is located in the hand-held enclosure for forming ultrasonic scanlines from the echo signals received by the elements of the array.
