Abstract

Ultraschall-Sende- und Empfangseinheit mit mindestens einem Wandler zur Erzeugung von Mehrfrequenz-Ultraschallsignalen und zum Empfang von durch ein Untersuchungsmedium beeinflussten, insbesondere reflektierten, gedämpften und/oder abgelenkten Ultraschallsignalen, wobei der Wandler ein zentrales Element und mindestens ein weiteres, um das zentrale Element herum angeordnetes Element aufweist, wobei die Elemente Ultraschallsignale unterschiedlicher Frequenz erzeugen und gleichzeitig emittieren und die vom Untersuchungsmedium beeinflussten Ultraschallsignale aller Frequenzen empfangen und die daraus gebildeten Empfangsignale einer Auswerteeinrichtung zuführen.
