Abstract: In an exemplary embodiment a transducer comb for an ultrasonic array or a compound scanner consists of a specifiable number of transducer elements joined together in a specific area formation, the width of each transducer element being smaller than its height. In the case of sonic heads of this type, given an optimum radiation or receiving power, respectively, the lateral resolution is to be significantly improved. This is achieved by a transducer element arrangement comprising a fine subsidivision of the transducer elements in such a manner that the width of each individual transducer element lies markedly below half the wavelength (.lambda./2) of the radiated, or received, ultrasonic waves, whereby, however, within the arrangement, in each instance, always a specified number of transducer elements of the fine subdivision is combined into a group through parallel-connection.
