X-ray phase-contrast imaging (XPCI) can extend the capabilities of conventional radiography and, by exploiting phase effects, make visible those details that lack enough absorption contrast [1]. Several approaches have been proposed for XPCI by using synchrotron radiation, microfocal and extended labortory sources [2]. We focus here on edge illumination [3] in view of its properties of high resolution, sensitivity, robustness and achromaticity [4-6]. The latter is of particular interest for the study reported here, where we used the direct beam from a bending magnet, aiming at making use of a spectral distribution as broad as possible.

Abstract
X-ray phase-contrast imaging (XPCI) can extend the capabilities of conventional radiography and, by exploiting phase effects, make visible those details that lack enough absorption contrast [1]. Several approaches have been proposed for XPCI by using synchrotron radiation, microfocal and extended labortory sources [2]. We focus here on edge illumination [3] in view of its properties of high resolution, sensitivity, robustness and achromaticity [4-6]. The latter is of particular interest for the study reported here, where we used the direct beam from a bending magnet, aiming at making use of a spectral distribution as broad as possible.File | Dimensione | Formato | |
