Hard-X-ray dark-field imaging using a grating interferometer

Imaging with visible light today uses numerous contrast mechanisms, including bright- and dark-field contrast, phase-contrast schemes and confocal and fluorescence-based methods. X-ray imaging, on the other hand, has only recently seen the development of a ...

Cellular dynamics explored with digital holographic microscopy

Benjamin Rappaz

Obtaining high resolution 3D quantitative images is critical for elucidating the relationship between cell dynamics and physiological or pathological processes. However the feasibility of such cellular dynamic studies is limited by the resolution of the 3D ...

Gd(III)-EPTPAC16, a new self-assembling potential liver MRI contrast agent: in vitro characterization and in vivo animal imaging studies

Lothar Helm

The recently reported amphiphilic chelate,

[Gd(EPTPAC_{16})(H_2O)]^{2-}

, forms supramolecular aggregates in aqueous solution by self-assembly of the monomers with a relaxometrically determined critical micellar concentration (CMC) of 0.34 mM. The effect ...

Shot noise, refractive index tomography and aberrations estimation in digital holographic microscopy

Florian Charrière

The present thesis develops some specific aspects of digital holographic microscopy (DHM), namely the effect of shot noise on the phase image accuracy, the use of DHM in micro-tomography and in aberrations evaluation of a microscope objective (MO). DHM is ...

A method for radiographic and tomographic imaging based on the absorption, phase shift, and scattering of x-rays

Christian David

The present invention relates to an interferometer for x-rays, in particular hard x-rays, for obtaining quantitative x-ray images from an object, comprising: a) an x-ray source, preferably a standard polychromatic x-ray source, b) a diffractive beam splitt ...

High-resolution differential phase contrast imaging using a magnifying projection geometry with a microfocus x-ray source

Christian David

Differential x-ray phase contrast imaging using a grating interferometer was combined with a magnifying cone beam geometry using a conventional microfocus x-ray tube. This brings the advantages of a magnifying cone beam setup, namely, a high spatial resolu ...

Fabrication of diffraction gratings for hard X-ray phase contrast imaging

Christian David

We have developed a method for X-ray phase contrast imaging, which is based on a grating interferometer. The technique is capable of recording the phase shift of hard X-rays travelling through a sample, which greatly enhances the contrast of low absorbing ...
