An ultrasound diagnostic device comprises a coefficient computation unit. The coefficient computation unit computes a coefficient on the basis of phase scattering in a plurality of received signals arranged in an element array direction. Beam data to which a phasing has been added is multiplied by the coefficient. A correction unit ensures that the coefficient does not get smaller than necessary on the basis of a transmission frequency. Excessive suppression of a main lobe component is thus eliminated or reduced. |
