Full-field X-ray nanoimaging is a widely used tool in a broad range of scientific areas. In particular, for low-absorbing biological or medical samples, phase contrast methods have to be considered. Three well established phase contrast methods at th

We are implementing an X-ray breast Computed Tomography (CT) system on the gantry of a dedicated single photon emission tomography system for breast Tc-99 imaging. For the breast CT system we investigated the relevance of the beam hardening artifact.

The intrinsic quality of an image is related to the concepts of spatial resolution, noise and contrast. A common method to measure these parameters is by using Edge Response Function measurements with a black mask. We investigated these parameters us

We report on high frame rate X-ray imaging tests with the Medipix2 single photon counting detector (single frames contain 256times256 pixel, 55 mum pitch, 13 bit counter) bump-bonded to a 300 mum thick silicon pixel detector. Image data are readout s

Light scattering processes in unconfined nematic liquid crystals have been investigated by means of time-resolved transmittance and static light scattering techniques. In time-resolved experiments, sample temperature has been modulated and different

In this work we exploit the advantages of using a bi-chromatic X-rays source coupled with a single photon counting pixel detector to perform a feasibility study for dual energy mammography. This technique allows enhancing the contrast between differe

The standard detector for mammography is the screen-film system, which consists of a photographic film coupled to an intensifying fluorescent screen; the latter improves the detection efficiency, but reduces the spatial resolution. The limited dynami
