Abstract :
X-ray CT is for nondestructive inspection in industrial field. In X-ray CT inspection, the problem is called ldquometal artifactrdquo on the reconstructed image is one of the biggest issue. This study aims to reduce metal artifact. Metal artifact is caused primarily by missing projection data from every projection angle. So, we propose the algorithm for correcting the missing projection data and confirm availability for nondestructive inspection in industrial field.
