X ray radiography and tomography are important tools in medicine as well as in life science
and materials science. Not long ago an approach called in-line holography based on simple …

X-ray phase contrast imaging is probably the most relevant among emerging x-ray imaging
techniques, and it has the proven potential of revolutionizing the field of diagnostic …

Phase contrast imaging (PCI) solves the basic limitation of x-ray imaging, ie, poor image
contrast resulting from small absorption differences. Up to now, it has been mostly limited to …

A novel x-ray phase contrast imaging technique based on coded apertures was recently
developed at University College London. This technique removes most limitations of …

X-ray imaging is a standard tool for the non-destructive inspection of the internal structure of
samples. It finds application in a vast diversity of fields: medicine, biology, many engineering …

Since Röntgen's discovery of X-rays just over a century ago the vast majority of radiographs
have been collected and interpreted on the basis of absorption contrast and geometrical …

Ever since the first demonstration of phase contrast imaging (PCI) in the 1930s by Frits
Zernike, people have realized the significant advantage of phase contrast over conventional …

In the last decade X-ray imaging based on phase contrast greatly advanced thanks to the
use of unmonochromatic synchrotron hard X-rays. The recent advances are going beyond …

Absorption-contrast x-ray imaging serves to visualize the variation in x-ray attenuation within
the volume of a given sample, whereas phase contrast allows one to visualize variations in x …

The exploitation of phase contrast appears to offer the tantalising possibility of creating the
biggest change in medical x-ray imaging since the invention of computed tomography. A …
