    Abstract: Provided is an apparatus and method for generating a virtual view in an image reconstruction system which uses multiple views. In the image reconstruction system which uses multiple views, the virtual view generating apparatus may receive original view projection images that are generated by emitting X rays toward an object via original views, three-dimensionally reconstruct the object by using the original view projection images, generate original view reprojection images by virtually emitting X-rays toward the reconstructed 3D object via the original views, estimate a motion of the reconstructed 3D object with respect to at least two of the original view reprojection images using a block-based motion estimation scheme, and generate an intermediate view projection image with respect to the at least two of the original view reprojection images by using information relating to the estimated motion.

    Abstract: An X-ray imaging apparatus includes an X-ray generator configured to generate X-rays and radiate the X-rays to an object; an X-ray detector configured to detect the X-rays that have passed through the object and convert the X-rays into a signal; and a controller configured to generate a single energy X-ray image and multiple energy X-ray images including a first X-ray image generated using an X-ray having determined energy band that is extracted from the X-rays detected by the X-ray detector. The multiple energy X-ray images further include a second X-ray image in which a specific substance is separated, which is image is generated using the image signals corresponding to the energy bands from the detected X-rays, respectively, and the controller is further configured to control a display to display the single energy X-ray image and the first X-ray image and the second X-ray image on a screen of the display.

    Abstract: An image reconstruction system, apparatus, and method employing a non-sequential scanning scheme using real-time feedback are provided. A projection information generating unit is configured to generate at least one piece of projection information by the X-ray irradiated to the object in the at least one viewpoint. A projection information comparing unit is configured to compare predicted intermediate projection information with measured intermediate projection information from the generated projection information. The predicted intermediate projection information is predicted from pieces of projection information generated from different viewpoints, and the measured intermediate projection information is measured in an intermediate viewpoint corresponding to the predicted intermediate projection information. A determining unit is configured to determine whether to irradiate the X-ray to the object in an additional viewpoint. An image reconstructing unit is configured to reconstruct the generated projection information, and to acquire an image representing the object.

    Abstract: Disclosed herein are a display apparatus which facilitates a simultaneous comparison of a plurality of images which respectively illustrate different features on one divided display screen such that the images are seamlessly displayed on the screen, and an image display method which is performable by using the apparatus. The display apparatus includes a memory configured to store a plurality of different types of images of an object, an input device configured to receive an input of a command relating to simultaneously displaying the different types of images, and a display device configured to display images. Upon receiving the command, the display device divides a screen upon which an image of the object is displayable into a first region within which a first image showing one portion of the object is displayed and a second region within which a second image showing the remaining portion of the object is displayed.
