Method and device for forming an image of an object, in which the following steps are performed: generating and transmitting a transmitted beam (B<+>) to a medium; receiving echo signals caused by the medium within a received beam (B<->); converting the echo signals into incoming electrical signals to form an image (P(r,z0, omega ); p(x,t), P(kx, omega )); wherein the transmitted beam and the received beam, respectively, is transformed into a virtual transmitted beam of a predetermined desired shape and a virtual received beam of a predetermined shape, respectively, to form the image (P(r,z0, omega ); p(x,t), P(kx, omega )) and during the transformation at least one spatial phase adjustment is applied. |
