Fig. 5From: 3D reconstruction of biological structures: automated procedures for alignment and reconstruction of multiple tilt series in electron tomographyAssessment on the convergence process. We monitor the coefficient of variation \(c_\text{v}\) on the middle tomogram slice as the number N of tilt series increases; \(c_\text{v}\) is implemented both with FBP (red diamond points, left y-axis) and wSIRT (blue circular points, right y-axis). For the iterative approach, the total number of iterations is 50 with a mixing parameters \(\alpha\) of 2; the original data were binned by 4Back to article page
