Abstract
The purpose of this study is to set up a non-destructive X-ray defect detection technique which can be applied to industry. The inner material information of the sample to be investigated is established by using the inherent character of X-ray (X-ray can penetrate most of material). The using of X-ray achieves the goal of non-destructive detection. To satisfy the requests for efficiency of industrial detection and ensure the reconstructed image which can possess a good recognition, this study adopts the Algebraic Reconstruction Technique（ART） as the core algorithm to do the X-ray image reconstruction under the limited projection angle. Furthermore, in this study, Multi-Value Image Reconstruction, Real Image Reconstruction and 3D Image Reconstruction which are based on the binary steering ART and the mixed ART. Finally, the techniques proposed by this study are a good candidate which can be applied to the industrial Automatic X-Ray Inspection field.
