The technology is directly parallel to TLSMD analysis.
It creates a model that includes a prediction of the blurring in the
original image, or in our case the blurring in the map generated by
Fourier transform of the original data. The difference is that in the
case of a photograph one is interested in the altered image rather than
the underlying model. In the case of a crystal structure one is interested
in the underlying model rather than the electron density map per se.
I have for a long time used the "motion-blurred photograph" parallel
to explain how TLSMD works. See for example page 3 of
