ABSTRACT:
A method and device for transmission of wide beam in ultrasonic diagnostic systems is disclosed. The method comprises: dividing an aperture of an ultrasonic probe into N sub-apertures; laterally dividing a focus into N sub-focuses, wherein the N sub-apertures correspond to the N sub-focuses respectively, each sub-aperture has M array elements which all focus on a sub-focus corresponding to said sub-aperture; and N and M are integers larger than 2; exciting the N sub-apertures by a pulse generator, so as to obtain a laterally stretched transmit acoustic filed, wherein the transmit acoustic fields of the N sub-apertures focus on the corresponding sub-focuses respectively; and accumulating the acoustic fields of the sub-apertures to form an acoustic field of a wide beam covering acoustic fields of all receive lines. The present invention makes it possible for the system to transmit wide beams covering all receive lines, by dividing the aperture of the probe into a plurality of sub-apertures and accumulating the acoustic fields of the sub-apertures.
