Abstract

Arising from K. S. Raines et al. Nature 463, 214–217 (2010)10.1038/nature08705 Raines et al. 1 propose a method, which they call ‘ankylography’, for three-dimensional structure determination using single-shot diffractive imaging (SSDI). But the conclusion without limitation that the three-dimensional structure of an object is “in principle encoded into a 2D diffraction pattern on the Ewald sphere” and may be inverted by SSDI is inadequately substantiated and conceptually misleading. Here I point out that SSDI in general suffers from a dimensional deficiency that limits the applicability of ankylography to objects that are small-sized in at least one dimension or that are approximately two-dimensional in some other way.
