TI  - Edge information diffusion based reconstruction (EIDR) for cone beam computed 
      laminography.
LID - 10.1109/TIP.2018.2845098 [doi]
AB  - Computed laminography (CL) is a prospective nondestructive testing technique for 
      flat object inspection in industrial applications. However, CL image 
      reconstruction is a challenging task because incomplete projection data are 
      acquired from the CL scan. When a conventional computed tomography (CT) 
      reconstruction method is applied to cone beam CL data, the vertical edges 
      (singularities in the z-direction) in the reconstructed image would be blurred. 
      On the contrary, the horizontal edges (singularities within slices) can be quite 
      accurately reconstructed. Based on this key observation, an edge information 
      diffusion method is developed, which fixes the horizontal edges and propagates 
      their values within the slices. An effective CL reconstruction method is then 
      proposed for flat object inspection by combining the edge information diffusion 
      procedure, which plays the role of regularization, with conventional CT image 
      reconstruction algorithms. Experiments on both simulated data and real data are 
      performed to verify the effectiveness of the proposed method. The results show 
      that the proposed method can effectively suppress the inter-slice aliasing and 
      blurring caused by incompleteness of the CL scan data, and that it outperforms 
      other state-of-the-art methods.
