Phase-contrast x-ray imaging (PCI) is an innovative method that is sensitive to the refraction
of the x-rays in matter. PCI is particularly adapted to visualize weakly absorbing details like …

A significant improvement over conventional attenuation-based X-ray imaging, which lacks
contrast in small objects and soft biological tissues, is obtained by introducing phase …

The medical imaging and therapeutic technologies that are based on the use of radiation
are reviewed briefly, with special emphasis on the recent developments of synchrotron …

The basic principles of x-ray image formation in radiology have remained essentially
unchanged since Röntgen first discovered x-rays over a hundred years ago. The …

Conventional radiography produces a single image of an object by measuring the
attenuation of an x-ray beam passing through it. When imaging weakly absorbing tissues, x …

In early stages of various pulmonary diseases, such as emphysema and fibrosis, the change
in X-ray attenuation is not detectable with absorption-based radiography. To monitor the …

X-ray chest radiography is an inexpensive and broadly available tool for initial assessment
of the lung in clinical routine, but typically lacks diagnostic sensitivity for detection of …

Phase-sensitive X-ray imaging methods can provide substantially increased contrast over
conventional absorption-based imaging, and therefore new and otherwise inaccessible …

Objective To introduce a novel X-ray technology, diffraction-enhanced X-ray imaging (DEI),
in its early stages of development, for the imaging of articular cartilage. DesignDisarticulated …

Diffraction enhanced imaging is a radiographic technique that derives contrast from an
object's x-ray absorption, refraction gradient and small angle scatter properties (extinction) …
