1. A backscattered X-ray image device comprising:
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;
a vibrator connected to the second slit plates and configured to vibrate the second slit plates; 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.
