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.

Abstract: A display device includes: a display substrate; a light amount control layer on the display substrate; a first polarizer on the light amount control layer; and a color conversion layer on the first polarizer. The color conversion layer includes a phosphor, the phosphor includes a quantum dot, the quantum dot including: a core; a first shell surrounding the core; and a second shell surrounding the first shell, and the quantum dot has a diameter ranging from about 2 nm to about 32 nm.
