[en] Since their discovery in 1895, X-rays have been used in many imaging methods. Computed Tomography (CT) stands out by being non-invasive 3D imaging method while classical X-rays imaging methods including CT return 2D images.
This master thesis aims to define the different steps of CT imaging, to develop the knowledge of the internship host company and to analyse the quantitative aspect of the CT reconstructions obtained with a custom-made CT-system (CT-Box). It also introduces a first industrial application that aims to evaluate the oil and water proportion inside a porous rock.
The thesis has been divided into 3 parts. The first part is dedicated to the study CT basics. The second characterises the CT-system such as its geometry and its acquisition system. The third part develops applications dedicated to analyse the accuracy, reliability and time repeatability of the reconstructions obtained with the CT-Box. In the last part, the feasibility of the industrial application is studied by an experimental simulation of the process.
The original results presented in this work are multiple: a quantitative study of tomographic reconstruction of objects scanned with the CT-Box and a solid understanding of the CT application. The possibility to discriminate water and oil in a porous media was demonstrated up to a certain level of precision.
At the end of this work, computed tomography now offers a wide range of possibilities for the company and a promising business sector to develop new innovative X-rays imaging solutions.
