摘要：
This paper presents the optimization of a speckle-based X-ray phase-contrast imaging setup. There are reported advances in techniques from the creation of a random speckle pattern to its characterization; the process of choosing the most suitable diffuser based on the patterns obtained using different types of phase-modulators; our experimental setup along with a discussion about its limitations and how to overcome them and we describe the procedure we implemented for speckle characterization and information retrieval from the acquired images. The obtained results are promising being comparable with thoses previously reported in literature. © 2023, Politechnica University of Bucharest. All rights reserved.
