ULTRASONIC ECHOGRAPH USING AT LEAST ONE PIEZOELECTRIC TRANSDUCER WITH A RANDOM PHASE SCREEN

摘要

Ultrasonic ultrasound system comprising at least one piezoelectric transducer 10, 13 ensuring the emission and / or reception of an ultrasonic exploration beam 20, characterized in that at least one piezoelectric transducer 10 is associated with a random phase screen 11 located in and movable relative to the scanning ultrasound beam 20, and in that means are provided for recording an ultrasound line e (t) for each alpha position of said random phase screen 11. /P P Application especially in ultrasound medical ultrasound and non-destructive testing of materials.
