Fig. 6

Tomogram views (XY, YZ, and XZ) of a 5-nm gold particle with respect to the number of tilt series N. A FBP is used. B wSIRT is used. While the image quality improves as N increases, the reconstruction still remain impaired by artifacts caused by the missing pyramid problem (equivalent to a missing cone problem when \(N\rightarrow \infty\)). Note artifacts are attenuated for wSIRT (50 iterations and \(\alpha =2\)) compared to FBP
