T1 - Absorption and phase contrast

WG Leader: Lucia Mancini

This Working Group focuses specifically on the reconstruction challenges in tomographic imaging based on detection of the phase and amplitude of the transmitted X-ray signal, leading to absorption and phase contrast. Both modalities can be reconstructed separately, but can also be used together in a single reconstruction procedure.

Research tasks for this Working Group include:
(a) Developing a procedure for fast imaging from limited data, based on incorporating sample-specific prior knowledge in the reconstruction method.
(b) Developing algorithmic techniques for accurate phase retrieval from single and from multiple projection images, which requires suppressing artefacts that currently limit the accuracy.
(c) Developing algorithmic techniques for combined absorption and phase contrast tomography.
