Fast and accurate X-ray fluorescence computed tomography imaging with the ordered-subsets expectation maximization algorithm

The ordered-subsets expectation maximization algorithm in X-ray fluorescence computed tomography allows image reconstruction with a large angular sampling interval but maintaining a high image quality.

Zone-doubled Fresnel zone plates for high-resolution hard X-ray full-field transmission microscopy

The use of zone-doubled Fresnel zone plates for sub-20 nm spatial resolution in full-field transmission X-ray microscopy and tomography at the hard X-ray regime (8-10 keV) is demonstrated.

X-ray grating interferometer for biomedical imaging applications at Shanghai Synchrotron Radiation Facility

A grating interferometer designed for biomedical imaging applications was installed at the BL13W beamline of Shanghai Synchrotron Radiation Facility. With the set-up, in situ carotid artery and carotid vein were visualized in a formalin-fixed mouse using X-rays without contrast agents.
