Fast diffraction‐enhanced imaging using continuous sample rotation and analyzer crystal scanning

Diffraction‐enhanced imaging (DEI) has high sensitivity and a wide dynamic range of density and thus can be used for fine imaging of biological and organic samples that include large differences in density. A fast DEI method composed of continuous fast sample rotations and slow analyzer crystal scan...

Description
Summary:Diffraction‐enhanced imaging (DEI) has high sensitivity and a wide dynamic range of density and thus can be used for fine imaging of biological and organic samples that include large differences in density. A fast DEI method composed of continuous fast sample rotations and slow analyzer crystal scanning was developed to shorten the measurement period. Fine sectional images of a biological sample were successfully obtained within a half measurement period of the conventional step‐scanning method while keeping the same exposure time. In addition, a fine three‐dimensional image of a rat tail was obtained with a 375 s measurement period. Fast diffraction‐enhanced imaging composed of continuous fast rotations of samples and slow scanning of analyzer crystals has been developed.
