Defence of Emile Barjou's thesis (I&S department)

This thesis is part of the XPulse project, which aims to develop an innovative mammography system using phase imaging and tomography to extract maximum information while reducing the patient's exposure to X-rays. This project is the result of collaboration between various players and this thesis is being carried out with ALPhANOV, the project coordinator, and LaBRI, the laboratory where I am doing my PhD. In this project, I worked on the processing of data acquired with the various imaging facilities. This involves pre-processing the raw data, tomographic reconstruction and phase extraction. For tomographic reconstruction, I evaluated the various implementations available to us and then developed customised software to meet the specific requirements of our facilities. The main constraint was memory management, with the usual data sets approaching one terabyte. For phase recovery, two methods were used during the project: free propagation and Hartmann mask imaging. My work in this area involved studying and then implementing the existing methods for processing such images, and then integrating them as effectively as possible into the processing chain.
