Abstract: Provided is a backscattered X-ray image device based on multi-sources. The backscattered X-ray image device includes an X-ray tube array configured to generate X-rays, first slit plates provided on the X-ray tube array and having a first slit through which the X-rays pass, second slit plates provided on the first slit plates and having second slits defined in a direction different from that of the first slit, and detectors provided on the second slit plates and having a narrow gap in the same direction as the first slit, the detectors being configured to detect a backscattered beam that is emitted from a subject receiving the X-rays.

Abstract: Provided is a high voltage driving device including a housing and a cathode, an anode, and an insulation structure, which are disposed in the housing. Here, the cathode and the anode are spaced apart from each other with the insulation structure therebetween. Also, the insulation structure includes a first solid insulator disposed adjacent to the cathode and a second solid insulator disposed adjacent to the anode. Also, the first solid insulator has first volumetric resistivity less than second volumetric resistivity of the second solid insulator, and the first solid insulator contacts the cathode.
