Abstract :
X-ray CT system is used for nondestructive inspection in industrial field. But there are some problems when we get the images of objects, namely rate of expansion, contrast and measurement area. This study aims at solving these problems by contriving oblique offset X-ray CT system. We improved Feldkamp algorithm which is the conventional 3D reconstruction method. Supportive experimental results are provided based on simulation phantom data.
