The method of operating an image device comprises receiving an input of virtual tissues modeled with an arbitrary shape and a quantitative feature, simulating a TOF change or a signal strength change of ultrasound data having penetrated the virtual tissues modeled with a speed-of-sound distribution or an attenuation coefficient distribution in a first and in a second direction, and creating an image pair representing the TOF change or the signal strength change, creating a speed-of-sound distribution image or an attenuation coefficient distribution image of each of the virtual tissues as a ground truth of an image pair created in the corresponding virtual tissue, and training a first neural network that reconstruct the speed-of-sound distribution image from an input image pair or training a second neural network that reconstructs the attenuation coefficient distribution image from the input image pair.

Method and apparatus for quantitative imaging using ultrasound data

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.

A mobile terminal includes a terminal body including a display unit formed on one surface thereof, a cover coupled to the terminal body such that it can be converted into a closed state in which the display is covered and an opened state in which the display unit is exposed, a signal generating unit configured to generate a state signal according to the closed state and the opened state, and a controller configured to control the display unit such that the display unit is activated in the opened state on the basis of the state signal.

Mobile terminal

The present disclosure provides a pouch for a mobile terminal and a mobile terminal having the same. The pouch includes a base defining a space for receiving at least part of a terminal body therein, a slide unit disposed within the base, and relatively slidable with respect to the base along a lengthwise direction of the terminal body, the slide unit supporting the terminal body, an elastic unit disposed between the base and the slide unit to apply an elastic force, a guide unit configured to guide the relative sliding of the slide unit, and a locking unit configured to lock and unlock the slide unit at and from a preset position of the base.

Pouch and mobile terminal having the same

A mobile terminal including a main body; a display unit arranged on a front side of the main body, and configured to display a video communication screen in a first direction when a video communication event occurs; a camera arranged in a lower end portion of the front side and configured to capture an image during the video communication event; a sensing unit installed in the main body, and configured to detect a motion of the main body in response to the video communication event; and a controller configured to switch a displaying direction of the video communication screen from the first direction to a second direction based on the detected motion of the main body.

Mobile terminal and method of controlling the mobile terminal

Disclosed is a mobile terminal in which while a rear case is coupled to or separated from a terminal body, a case is slopingly moved with respect to the terminal body, so a camera hole of the rear case can be freely moved without being restricted by a camera mounting part protruded from the terminal body.

A mobile terminal includes: a terminal main body having a window formed on a front surface thereof; an interface disposed at the side of the main body and electrically connected with an external device; and a cap module configured to open and close the interface, wherein the cap module includes: a cover configured to cover the interface; and a movement mechanism configured to rotate the cover toward a front side or a rear side of the main body from the side of the main body and slidably moving a rotational center of the cover by interworking with a rotation of the cover.

A method of forming fine patterns of a semiconductor device is provided. The method includes forming plural preliminary first mask patterns, which are spaced apart from each other by a first distance in a direction parallel to a surface of a substrate, on the substrate; forming an acid solution layer on the substrate to cover the plural preliminary first mask patterns; forming plural first mask patterns which are spaced apart from each other by a second distance larger than the first distance, of which upper and side portions are surrounded by acid diffusion regions having first solubility; exposing the first acid diffusion regions by removing the acid solution layer; forming a second mask layer having second solubility lower than the first solubility in spaces between the acid diffusion regions; and forming plural second mask patterns located between the plural first mask patterns, respectively, by removing the acid diffusion regions by the dissolvent.

Methods of forming fine patterns of semiconductor device

Methods of forming a pattern and methods of fabricating a semiconductor device having a pattern are provided, the methods include forming a self-assembly induction layer including a first region and a second region on a semiconductor substrate. A block copolymer layer is coated on the self-assembly induction layer. A first pattern, a second pattern and a third pattern are formed by phase separating the block copolymer. At least one of the first, second and third patterns may be removed to form a preliminary pattern. An etching process may be performed using the preliminary pattern as an etching mask. The first pattern contains the same material as that of the second pattern, and the third pattern contains a material different from that of the first pattern.
