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.
Claims14
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.
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;
- rotating choppers provided on the first slit plate to allow the X-rays to selectively pass therethrough so as to generate a pencil beam;
- detectors provided on the rotating choppers and configured to detect a backscattered beam that is emitted from a subject receiving the X-rays;
- second slit plates provided between the detectors and the first slit plates and having second slits extending in a direction different from that of the first slit;
- and
- a conveyor belt provided on the detectors and configured to hold the subject,
- wherein the rotating choppers comprise lower rotating choppers between the first slit plates and the second slit plates.
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;
- middle rotating choppers provided between the first slit plates and 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.
