DETECTOR DEVELOPMENT FOR PROTEIN CRYSTALLOGRAPHY Tomographic Measurements

For this experiment a metal screw (M12) rotating

with a frequency of 4000 turns/min was

illuminated with a parallel 8 keV beam (x-ray

tube), whilst the radiographic image was

continuously recorded with the 2D detector. By

applying the special time resolution technique,

the data were cut into 18 separate images

corresponding to angular intervals of 20 deg each.

These 2D radiograms enable to visualize the rapid

movement of the sample, to obtain 2D

tomograms at any vertical cut, and, eventually, to

obtain a 3D image by setting the 2D tomograms

together.
