Figure 7
Reconstructive images of PCB and the curves of pixel value along the white line. (A1)–(A4) were acquired using the inclined detector method, (B1)–(B4) were acquired using the ordinary detecting method; some radial artifacts can be seen in the images due to few projections used in the reconstruction. The number of iterations for each pair are 1, 4, 10 and 50, respectively. Time cost is ∼13 min per iteration. |
