In such a device, an ultrasonic transducer system is arranged in a movable fashion inside a water-filled applicator. The transducer system can rotate about the axis of symmetry of the applicator and can be swivelled about such an axis of rotation situated near the plane of the applicator opening, for which purpose the transducer system is arranged inside the applicator on a swivellable bracket. In the operating method provided, the ultrasonic transducer system rotates continuously or in steps about the central axis (I) in a prescribable angular position with respect to the application opening, it being possible in each azimuthal angular position of the ultrasonic transducer system (125) to change the imaging angle by tilting about the foot of the bracket (120). In the reproduction of the image on the viewing screen (31) of an image signal processing device (30), it is possible to generate a three-dimensional impression of the image, especially by swivelling to and fro in the angular range provided. For this purpose, for example a function generator (182), in particular a triangular wave oscillator is connected to the nominal-frequency selector (180) in the associated control device (175). As an alternative to this, a control device can be realised by a processor system (190) to which the prescribed functions are fed in a software fashion. <IMAGE>
