Abstract: Disclosed herein is an X-ray image apparatus having an improved rotating unit for preventing a blind spot in which an X-ray-generating unit is not rotated from being generated. The X-ray image apparatus includes an X-ray-generating unit configured to generate X-rays and radiate the X-rays, an X-ray-detecting unit configured to detect the X-rays radiated from the X-ray-generating unit, and a rotating unit configured to rotate the X-ray-generating unit. Here, the rotating unit includes a rotating frame coupled to one side of the X-ray-generating unit; a protrusion configured to protrude from one side of the rotating unit; and a stopper being in contact with the protrusion to halt a rotation of the rotating frame and being provided such that the stopper can be moved in a preset zone. Since the stopper securing the rotating frame of the rotating unit can be moved in the preset zone, it is possible to prevent a blind spot caused by a restriction of the rotation of the rotating frame from being generated.

Abstract: A collimator for adjusting the shape of a region irradiated by radiation and a control method thereof. The collimator includes a plurality of irises to adjust the shape of the irradiation region, a light source outputting light to display the irradiation region, a reflective mirror to adjust a path of light radiated from the light source toward the irradiation region, and an image output unit outputting to the irradiation region a visible image representing the shape of a target object for radiography or a mark indicating the center of the radiation region.

Abstract: A contents transmission system, a method of playing contents using an integration media play program, a method of transmitting contents using media format transcoding function, and a method of deciding whether the contents are transmitted. A home server of the contents transmission system includes a connector connected to a peripheral apparatus for interfacing various information transceived between the connector and the peripheral apparatus; a contents storage storing contents; and a contents list management unit reading out a list of contents stored in the peripheral apparatus, determining whether the read list is same as a contents list stored in the home server, and receiving untransmitted contents from the peripheral apparatus and storing the untransmitted contents in the contents storage when the contents lists are not same as each other.
