X-ray phase-contrast microscopy and microtomography.
In-line phase contrast enables weakly absorbing specimens to be imaged successfully with x-rays, and greatly enhances the visibility of fine scale structure in more strongly absorbing specimens. This type of phase contrast requires a spatially coherent beam, a condition that can be met by a microfocus x-ray source. We have developed an x-ray microscope, based on such a source, which is capable ...
متن کاملRecent developments in X-ray projection microscopy and X-ray microtomography applied to materials science
After a long period of sleeping, there is recently a spectacular revival of X-ray microscopy due to the progress in X-ray sources (synchrotron radiation), X-ray optics, and X-ray detectors. However most of the attempts in this field concern the use of soft X-rays to observe, with an improved resolution, biological specimens in their wet environment. In opposition to these trends, we try to demo...

First, X-ray computed to...
متن کاملX-ray microtomography in biology.
Progress in high-resolution X-ray microtomography has provided us with a practical approach to determining three-dimensional (3D) structures of opaque samples at micrometer to submicrometer resolution. In this review, we give an introduction to hard X-ray microtomography and its application to the visualization of 3D structures of biological soft tissues. Practical aspects of sample preparation...
متن کاملX-ray microtomography of bones and teeth.
X-ray microtomography is a miniaturized version of computerized axial tomography with a resolution of the order of micrometres. In the biomedical field it is particularly useful in the study of hard tissue because of its ability to accurately measure the linear attenuation coefficient. From this, the mineral concentration can be computed, which is one measure of bone quality. Using microtomogra...
