Electron tomography and holography in materials science
TLDR
An overview of the techniques of electron tomography and electron holography is presented and their capabilities with the aid of case studies that span materials science and the interface between the physical sciences and the life sciences are demonstrated.Abstract:
The rapid development of electron tomography, in particular the introduction of novel tomographic imaging modes, has led to the visualization and analysis of three-dimensional structural and chemical information from materials at the nanometre level. In addition, the phase information revealed in electron holograms allows electrostatic and magnetic potentials to be mapped quantitatively with high spatial resolution and, when combined with tomography, in three dimensions. Here we present an overview of the techniques of electron tomography and electron holography and demonstrate their capabilities with the aid of case studies that span materials science and the interface between the physical sciences and the life sciences.read more

Atomic resolution imaging in two and three dimensions
TL;DR: In this paper, the authors explored theoretical aspects of scanning transmission electron microscopy (STEM) and the comparison of simulation with experiment and found that quantitative agreement between theoretical and experimental images is possible provided that theory suitably accounts for the spatial incoherence of the source, and that experimental images are placed on an absolute scale with respect to the incident beam current.

Structural characterization of ZnS nanocrystals with a conic head using HR–TEM and HAADF tomography
TL;DR: In this article, the authors obtained ZnS nanocrystals with an apparent triangular head, which is not the frequently-reported pyramid, but rather a cone consisting of not only low energy planes but high Miller-index planes.

Representation of a Function by Its Line Integrals, with Some Radiological Applications
TL;DR: In this paper, a method for finding a real function in a finite region of a plane given its line integrals along all straight lines intersecting the region was given, and the solution found is applicable to three problems of interest for precise radiology and radiotherapy: (1) the determination of a variable x-ray absorption coefficient in two dimensions, (2) the distribution of positron annihilations when there is an inhomogeneous distribution of the positron emitter in matter, and (3) a variable density of matter with constant chemical composition, using the energy loss

Iterative methods for the three-dimensional reconstruction of an object from projections
TL;DR: It is shown that in general ART produces erroneous reconstructions, and an alternative iterative method is proposed which will give correct reconstructions under certain conditions.
