Abstract: An X-ray imaging apparatus is proposed. The X-ray imaging apparatus is configured to capture first and second X-ray images having examination object's alignment positions different from each other, the X-ray imaging apparatus including an imaging part configured to include a generator and a detector facing each other with an examination object interposed therebetween, and rotate the generator and the detector about a rotation axis therebetween to capture each of the first and second X-ray images, and an examination object alignment part configured to arrange the examination object between the generator and the detector, wherein a position of at least a part of the examination object alignment part is variable, so as to move and align the examination object to a first alignment position for capturing the first X-ray image and a second alignment position for capturing the second X-ray image, respectively.

Abstract: A touch interface system and a method for providing a touch interface by detecting a change in a pixel characteristic in a pixel selected with a sensing terminal. The touch interface system includes the sensing terminal to select a location corresponding to a pixel on a display unit, and a display processing module to change a pixel characteristic of the selected pixel to generate a processed pixel on the display unit. The sensing terminal in response recognizes the pixel with a changed pixel characteristic as the processed pixel, and the display processing module communicates with the sensing terminal to determine the location of the processed pixel. Accordingly, the location of the processed pixel may be received as a user input.
