Abstract
Reconstruction from a tilt series of electron micrographs is based on the assumption that each image represents a projection through the specimen, and that the 3D information can be recovered by “back-projecting” all the images in the correct geometry. We use algorithms that are integrative (back-projection or Fourier inversion) or iterative (algebraic or maximum entropy methods). In practical tomography, we can only record a finite set of images at a dose low enough to avoid radiation damage, yielding noisy tomograms with missing information. The quality of the tomograms depends on the algorithmic details, but also on the pre-processing of the tilt series images, and post-processing of the tomographic volume.
