X-ray phase-contrast imaging.
 
X-ray phase-contrast imaging is an emerging technique for visualising the inner structure of objects with high contrast. The method analyses the phase shift of x-rays caused by a sample in the beam rather than their absorption as done in conventional x-ray imaging. Due to its higher sensitivity to small density differences, phase-contrast imaging often yields superior results compared to absorption imaging. X-ray phase-contrast imaging has found applications in various fields such as biomedical imaging, materials science, and security screening and a number of different methods have been developed in the last decades.
 
My research at Diamond focusses on the development and implementation of techniques for x-ray phase-contrast imaging at I13 Beamline. Several methods for performing phase-sensitive imaging have been developed in the last decades, including x-ray grating interferometry. Recently, methods using x-ray near-field speckles have attracted increasing interest as they combine high sensitivity quantitative imaging with a simple experimental setup. For my PhD project I will be mainly working on the development and implementation of x-ray speckle-based imaging and grating interferometry at I13, also making these techniques available for users.
 
I am also involved in research on other x-ray imaging techniques here at I13, such as ptychography and in-line phase-contrast imaging.
 
My role as a PhD student at I13 (in collaboration with University College London) mainly entails research activities. In the future, I hope to be able to also provide some user support.
