Abstract:
A method and apparatus for reconstructing an image and a medical image system are provided. An image reconstruction processing method may include acquiring an initial value with respect to a tomographic image of an object to be inspected, initializing an auxiliary variable, acquiring one or both of a weighted value and an error value, based on a measured value, transforming a measured image signal, updating the auxiliary variable using a transform coefficient used to transform the measured image signal, and updating the measured value using the updated auxiliary variable, and one or both of the acquired weighted value and the error value.
Abstract:
A user terminal device and a displaying method thereof are provided. The user terminal device includes a display configured to display a first screen on a display which is divided by a folding line into a first area and a second area, the second area being larger than the first area with reference to a folding line and including an exposure area that is exposed while the display is folded along the folding line such that the first area faces the second area, a detector configured to detect, while the first screen is displayed, a first folding interaction of folding the display such that the first area faces the second area and a second folding interaction of folding the display such that a first cover corresponding to the first area faces a second cover corresponding to the second area, and a controller configured to, in response to detecting the first folding interaction, display a second screen related to the first screen on the exposure area, and in response to the second folding interaction being detected, display a third screen related to the first screen on the first area or the second area.
Abstract:
An electronic device for displaying images is provided. The electronic device includes a display displaying a first partial image of an image, a memory, and a processor. The processor is configured to designate a first object included in the first partial image if a first input for designating the first object is received, store first information associated with the first object in the memory, display, on the display, a first graphical object associated with the first object if the image displayed on the display is switched from the first partial image to a second partial image of the image, and switch the image displayed on the display from the second partial image to a third partial image of the image including the first object using the first information if a second input for selecting the first graphical object is received.
Abstract:
An electronic device and method are provided, the electronic device includes a first display configured to display a screen, a second display including a first surface facing the screen of the first display in a first state and a second surface opposing the first surface, a connector pivotally connecting the first display and the second display with each other, and a processor controlling display of at least some objects among a plurality of objects displayed on the screen of the first display on the second display, based on an angle between the first display and the second display. The method displays a screen on the first display, and displays at least some objects among a plurality of objects displayed on the screen of the first display on the second display, based on an angle between the first display and the second display.
Abstract:
A radiography apparatus and a method for controlling the radiography apparatus are provided. The radiography apparatus includes a radiographer configured to acquire a first radiation image of a subject before a contrast reagent is injected into the subject, and acquire a second radiation image of the subject after the contrast reagent is injected into the subject. The radiography apparatus further includes an image processor configured to calculate a difference between data of a pixel of the first radiation image and data of a pixel of the second radiation image, for each of pixels of the first radiation image, and acquire an image of the subject based the difference for each of the pixels of the first radiation image.
Abstract:
An X-ray apparatus includes an image separator configured to separate an X-ray image of an object into material images representing materials in the object; a parameter determiner configured to determine a width of a material of interest (MOI) based on the material images, and determine an enhancement parameter configured to enhance contrast of the MOI according to the width of the MOI; and an image enhancer configured to separate the X-ray image into detailed images respectively including spatial frequencies of different frequency bands, enhance each of the detailed images according to the enhancement parameter, and synthesize the enhanced detailed images to generate an enhanced image.
Abstract:
An X-ray imaging apparatus and a method for generating X-ray images are provided. The X-ray imaging apparatus includes an X-ray source configured to irradiate X-rays to a subject, and an X-ray detector configured to detect X-rays penetrating the subject, and generate a frame image including pieces of X-ray data for energy bands. The X-ray imaging apparatus further includes an image divider configured to divide the frame image into images of substances, using the pieces of the X-ray data, and an image generator configured to restore the frame image by performing motion compensation on an image of a first substance of the frame image, among the images of the substances of the frame image, and an image of the first substance of a previous frame image.
Abstract:
