Metal artifact removal (MAR) analysis for the security inspections using the X-ray computed tomography

• The X-ray image is used for the nuclear inspections which are made by the image processing.
• Nuclear security has been performed for counterterrorism.
• Easy and fast inspections are needed.
• Metal shows the characteristics of the noises.

Using the metal artifact property, it is analyzed for the X-ray computed tomography (CT) in the aspect of the security on the examined places like airport and surveillance areas. Since the importance of terror prevention strategy has been increased, the security application of X-ray CT has the significant remark. One shot X-ray image has the limitation to find out the exact shape to property in the closed box, which could be solved by the CT scanning without the tearing off the box in this work. Cleaner images can be obtained by the advanced technology if the CT scanning is utilized in the security purposes on the secured areas. A metal sample is treated by the metal artifact removal (MAR) method for the enhanced image. The mimicked explosive is experimented for the imaging processing application where the cleaner one is obtained. The procedure is explained and the further study is discussed.
