Abstract: There is provided a 3D image generation method and apparatus. A 3D image generation method according to an embodiment includes outputting a signal to an object from at least one point, receiving the signal reflected by the object at one or more points, and generating a 3D image of the object based on a temporal feature and a spectral feature of the signal reflected by the object.

Abstract: A method of operating an image device operated by at least one processor is provided. The method of operating an image device comprises generating beamformed RF-mode images including phase shift information for each incident angle by using multi-angle ultrasound-echo data, generating phase shift maps representing a displacement of speckle pattern between adjacent beamformed RF-mode images, and obtaining a speed-of-sound distribution image corresponding to the phase shift maps by using a deep neural network which is trained to reconstruct speed-of-sound distribution of a tissue from training phase shift maps.
