摘要： The present disclosure relates to a method for generating a synthetic image. In the method, image data is generated using a receiving dynamic beamforming method, image data is generated using a synthetic aperture beamforming method, and the image data generated using the receiving dynamic beamforming method and the image data generated using the synthetic aperture beamforming method are synthesized with being applied with weighting factors according to advancing distances of ultrasonic waves. By using a zone blending method, in which image data according to a receiving dynamic beamforming method is mainly used for an ultrasonic image having a predetermined depth or less, and image data according to a synthetic aperture beamforming method is mainly used for an ultrasonic image having any other depth, a grating lobe and distortion of image brightness are eliminated. In addition, the non-uniformity of the image is compensated, and a uniform energy density is acquired even in an area near a virtual transmission sound source.
