The -3dB and -6dB contours of the acoustic field show that an apodised transducer shows a large depth of field, a very desirable result if medical images are to be obtained from deep structures without lowering the ultrasound frequency.

Geschichtliches und Statistischesmodelled, without approximation, even for strong curvatures. The extension to lossy, dispersive, and even solid, media may be made relatively straightforwardly. Propagation in nonlinear media offers more of a challenge, and the method is being extended to deal with that case.

Verarbeitung des Teers und Ammoniakwassersa single layer broadband transducer for harmonic imaging in order to compare performances of both transducers. We have observed that the two-layer transducer has better performances than the broadband single layer device. We obtain a sensitivity gain around 40 % and a resolution gain around 25 %.
