Procedure for the manufacturing of a piezoelectric ceramics radiating surface, of the type that is used in a powerful ultrasound transducer, with said transducer being next to an electrical impedance adaptation network, a powerful amplifier, a signal generator, a control unit, with the transducer also comprising an external casing, said piezoelectric ceramics between some electrodes, an absorbent material between the casing and the piezoelectric ceramics and an adaptation layer, characterized in that piezoelectric ceramics radiating surface U2 is defined as part of a surface U1 that contains an arch A2 and is limited by two projections p1 and p2, without necessarily containing them and which are obtained by applying the procedure.
