A new solution to the curved Ewald sphere problem for 3D image reconstruction in electron microscopy
Publikováno v:
Ultramicroscopy. 224
We develop an algorithm capable of imaging a three-dimensional object given a collection of two-dimensional images of that object that are significantly influenced by the curvature of the Ewald sphere. These two-dimensional images cannot be approxima

We outline an image reconstruction algorithm that is capable of reconstructing an object from the averaged Fourier intensity of finite crystals of that object with arbitrary lattice occupancies. The algorithm is tested via simulations where the 3-dim

Diffraction patterns from small protein crystals illuminated by highly coherent X-rays often contain measurable interference signals between Bragg peaks. This coherent `shape transform' signal introduces enough additional information to allow the mol

The development of serial femtosecond crystallography (SFX) at X-ray free electron lasers (X-ray FELs) allows for the use of tiny protein crystals down to just a few unit cells along an edge, measured at physiological temperatures, and with a time re

It is demonstrated here that the exit wave-field of objects from two different planes along the wave propagation axis can be retrieved from their coherently summed far-field diffraction intensity. This is achieved through the application of an iterat

An additional step to traditional iterative phase retrieval algorithms is described that allows the reconstruction of an image from the product of its sufficiently sampled far-field diffraction intensity and a second signal. The iterative phasing alg

X-ray free-electron laser diffraction patterns from protein nanocrystals provide information on the diffracted amplitudes between the Bragg reflections, offering the possibility of direct phase retrieval without the use of ancillary experimental diff

Serial femtosecond nanocrystallography (SFX) is a form of x-ray coherent diffraction imaging that utilises a stream of tiny nanocrystals of the biological assembly under study, in contrast to the larger crystals used in conventional x-ray crystallogr

The problem of reconstructing multiple objects from the average of their diffracted intensities is considered. Three cases of technical interest are studied. The first is where the incoherent average is measured over a single object that adopts a num
