Abstract: A support for a transducer for emitting and/or receiving ultrasonic signals in a given angular sector, comprising a series of substantially coaxial, loop-shaped elements which are axially arranged one behind the other. The first element can be arranged on a surface of an object to be examined, while the transducer is secured in the last element. Every two successive elements can pivot through a given angle with respect to each other. The total angular distance of the assembly formed by the elements at least equals the chosen angular sector. When the orientation of the transducer changes with respect to the surface, the distance between the transducer and the surface is not substantially varied.
