X-ray grating interferometry, as a powerful nondestructive imaging tool in fields like biology and medical tests, works well with conventional X-ray tubes, and provides three kinds of information, the attenuation image, the phase-contrast image and the dark field image, with higher contrast. However, the limited field of view of the sample due to the limited size of gratings and detector hinders the...
X-ray grating interferometry is a powerful nondestructive tool in many fields, such as medicine, biology and material science. It works well with conventional X-ray tubes and multiple information, that is the attenuation image, differential phase-contrast (DPC) image and the dark-field image, can be obtained in a single scanning. The latter two images can provide additional and complementary information...
X-ray grating-based imaging is a powerful nondestructive tool in many fields. It works well with conventional X-ray tubes and multiple information, that is the attenuation image, the phase-contrast image and the dark-field image, can be obtained in a single scanning. Phase-stepping approach is the gold standard for information retrieval. One of the gratings moves relatively in the along the transverse...
X-ray dark-field imaging can provide insight into the small-angle scattering properties of the image objects. The grating interferometry can offer the attenuation contrast, phase contrast and small-angle scattering contrast simultaneously, in which the small-angle scattering contrast, i.e. the dark-field image, show unique and complementary information to the previously reported attenuation contrast...
