摘要： A tomography apparatus and a method of processing a tomography image are provided. The tomography apparatus includes a data acquirer configured to acquire a first image corresponding to a first time point and a second image corresponding to a second time point, based on data that is obtained from performing tomography on a moving object, acquire first information indicating a movement of the object between the first time point and the second time point, and determine a motion reliability indicating a degree to which the movement of the object corresponds to a physical movement, based on the first information. The tomography apparatus further includes an image reconstructor configured to reconstruct a target image indicating the object at a target time point, based on the motion reliability.

摘要： A tomography apparatus includes a data obtainer and an image processor. The data obtainer performs a tomography scan on a moving object and obtains raw data of the object The image processor reconstructs a first tomography image of the object for a first slice section in a first phase from the raw data and reconstructs a second tomography image in a second phase, which is different from the first phase, for the first slice section of the object by using the raw data. The image processor also generates motion information indicating a three-dimensional (3D) motion of the object. The second phase is a phase beyond a phase range of the raw data.

摘要： An X-ray imaging apparatus displays a bone or soft tissue image of an X-ray image, which corresponds to a region selected by a user, thereby reducing a diagnosis time. In addition, an X-ray imaging system transmits a first energy X-ray image and a second energy X-ray image to a central image management system, and a user control apparatus receives the images from the central image management system and displays a bone or soft tissue image corresponding to the selected region, thereby reducing burden imposed on server capacity of the central image management system as well as reducing a diagnosis time.

摘要： A computed tomography (CT) image processing apparatus and a CT image processing method are provided. The CT image processing apparatus may generate a virtual monochromatic image (VMI) by applying a weight to each of first, second, and third images corresponding to three different energy ranges. The CT image processing apparatus may set a region of interest (ROI) on a CT image, determine a VMI at an energy level at which a CNR of the ROI is at a maximum among a plurality of VMIs, and display the determined VMI.

摘要： A method and apparatus correct a computed tomography (CT) image with motion artifacts. The method of correcting a CT image may include: obtaining a reconstruction image of an object by reconstructing an X-ray projection image; measuring a parameter value related to motion artifacts that occur due to movement of the object in at least one of the X-ray projection image or the reconstruction image; calculating a correction possibility for the reconstruction image based on the measured parameter value; and determining whether to perform correction on the reconstruction image based on the calculated correction possibility.
