Longuefosse, Arthur. "Apprentissage profond pour la conversion d’IRM vers TDM en imagerie thoracique." Electronic Thesis or Diss., Bordeaux, 2024. http://www.theses.fr/2024BORD0489.
Повний текст джерелаThoracic imaging faces significant challenges, with each imaging modality presenting its own limitations. CT, the gold standard for lung imaging, delivers high spatial resolution but relies on ionizing radiation, posing risks for patients requiring frequent scans. Conversely, lung MRI, offers a radiation-free alternative but is hindered by technical issues such as low contrast and artifacts, limiting its broader clinical use. Recently, UTE-MRI shows promise in addressing some of these limitations, but still lacks the high resolution and image quality of CT, particularly for detailed structural assessment. The primary objective of this thesis is to develop and validate deep learning-based models for synthesizing CT-like images from UTE-MRI. Specifically, we aim to assess the image quality, anatomical accuracy, and clinical applicability of these synthetic CT images in comparison to the original UTE-MRI and real CT scans in thoracic imaging. Initially, we explored the fundamentals of medical image synthesis, establishing the groundwork for MR to CT translation. We implemented a 2D GAN model based on the pix2pixHD framework, optimizing it using SPADE normalization and refining preprocessing techniques such as resampling and registration. Clinical evaluation with expert radiologists showed promising results in comparing synthetic images to real CT scans. Synthesis was further enhanced by introducing perceptual loss, which improved structural details and visual quality, and incorporated 2.5D strategies to balance between 2D and 3D synthesis. Additionally, we emphasized a rigorous validation process using task-specific metrics, challenging traditional intensity-based and global metrics by focusing on the accurate reconstruction of anatomical structures. In the final stage, we developed a robust and scalable 3D synthesis framework by adapting nnU-Net for CT generation, along with an anatomical feature-prioritized loss function, enabling superior reconstruction of critical structures such as airways and vessels. Our work highlights the potential of deep learning-based models for generating high-quality synthetic CT images from UTE-MRI, offering a significant improvement in non-invasive lung imaging. These advances could greatly enhance the clinical applicability of UTE-MRI, providing a safer alternative to CT for the follow-up of chronic lung diseases. Furthermore, a patent is currently in preparation for the adoption of our method, paving the way for potential clinical use
Vicente, David. "Modèles de Mumford-Shah pour la détection de structures fines en image." Thesis, Orléans, 2015. http://www.theses.fr/2015ORLE2055/document.
Повний текст джерелаThis thesis is a contribution to the fine tubular structures detection problem in a 2-D or 3-D image. We arespecifically interested in the case of angiographic images. The vessels are surrounded by noise and thenthe question is to segment precisely the blood network. The theoretical framework of our work is thecalculus of variations and we focus on the Mumford-Shah energy. Initially, this model is adapted to thedetection of volumetric structures extended in all directions of the image. The aim of this study is to buildan energy that favors sets which are extended in one direction, which is the case of fine tubes. Then, weintroduce a new unknown, a Riemannian metric, which captures the geometric structure at each point ofthe image and we give a new formulation of the Mumford-Shah energy adapted to this metric. Thecomplete analysis of this model is done: we prove that the associated problem of minimization is wellposed and we introduce an approximation by gamma-convergence more suitable for numerics. Eventually,we propose numerical experimentations adapted to this approximation

Повний текст джерелаA large family of oxides has been investigated by electron energy loss spectroscopy in order to correlate electron excitation spectra to crystal structure and chemical composition. This study has been performed with a magnetic spectrometer of high energy resolution (sub 1 eV over the loss range 0-2000 eV) and in a STEM with high spatial resolution (a few nm), which is quite suited to inhomogeneous specimens. This manuscript deals with two major developments. Lt describes: 1) A quantitative elemental analysis method on thin foils. Two approaches have been followed to extract local concentration measurements from the intensities of characteristic core edges. The first one uses subtraction of background fitted with a power law curve and we have evaluated the precision of the measurement and uncertainties sources. The second one consists in modelizing the experimental spectrum as the superposition of several computed contributions. We have thus improved the experimental determination of M45 cross sections for lanthanides. 2) A high resolution spectroscopy tool on thin foils, for both valence electrons and atomic orbitals excitations. In the first case, the concept of plasmon bas been discussed in these compounds which differ noticeably from the simple jellium, and the parameterization of the dielectric constants is used to define the electron population for a given excitation feature. Ln the second case, the fine structure on the threshold and in the vicinity of the absorption edges have been recorded for different site symmetries and local charge densities. The intensity of white lines on transition metal L23 edges and rare earth metal M45 edges has been analyzed. For oxygen K edges, the crystal field affect has been discriminated from the d band occupancy one

Повний текст джерелаThroughout this work, the main objective is to validate the relevance of construction and use of geometric or parametric 3D models BIM or hBlM-oriented for numerical analyzes. These include structural studies in the case of historic buildings, as well as planning for restoration work, energy renovation and rehabilitation. Complementary data mining and use of point clouds for the detection, segmentation and extraction of geometric features have also been integrated into the work and proposed methodology. The process of data processing, geometric or parametric modeling and their exploitation, proposed in this work, contributes to improve and understand better the constraints and stakes of the different configurations and conditions related to the case studies and the specific constraints specific to the types of constructions. The contributions proposed for the different geometric and parametric modeling methods from point clouds are addressed by the construction of geometric models BIM or hBlM-oriented. Similarly, the process of surface detection, extraction of data and elements from point clouds are presented. The application of these modeling methods is systematically illustrated by different case studies, all of whose relative work has been carried out within the framework of this thesis. The goal is therefore to demonstrate the interest and relevance of these numerical methods according to the context, needs and studies envisaged, for example with the spire of the Senlis cathedral (Oise) and the Hermitage site (Oise). Numerical analyzes with finite element method are used to validate the relevance of these approaches

Повний текст джерелаThis thesis deals with the topological gradient method applied in imaging. Particularly, we are interested in object detection. Objects can be assimilated either to edges if the intensity across the structure has a jump, or to fine structures (filaments and points in 2D) if there is no jump of intensity across the structure. We generalize the topological gradient method already used in edge detection for images contaminated by Gaussian noise, to quasi-linear models adapted to Poissonian or speckled images possibly blurred. As a by-product, a restoration model based on an anisotropic diffusion using the topological gradient is presented. We also present a model based on an elliptical linear PDE using an anisotropic differential operator preserving edges. After that, we study a variational model based on the topological gradient to detect fine structures. It consists in the study of the topological sensitivity of a cost function involving second order derivatives of a regularized version of the image solution of a PDE of Kirchhoff type. We compute the topological gradients associated to perforated and cracked 2D domains and to cracked 3D domains. Many applications performed on 2D and 3D blurred and Gaussian noisy images, show the robustness and the fastness of the method. An anisotropic restoration model preserving filaments in 2D is also given. Finally, we generalize our approach by the study of the topological sensitivity of a cost function involving the m − th derivatives of a regularization of the image solution of a 2m order PDE

Повний текст джерелаLn this work, molecular complexes of the first period transition elements are studied by X-ray absorption spectroscopy. The first point is devoted to a fundamental study of the absorption edge: we take advantage of the versatility of coordination chemistry, to study complexes, with different stereochemistries and electronic structures. Ln the case of isolated molecules with well-known structures, we point out the influence of oxidation and spin states of the metallic ion, symmetry, metal-ligand distances and remote neighbours shells upon the edge. We discuss the transitions towards bound states using a molecular orbital approach. As for the XANES part of the spectrum, we use multiple scattering theory. We discuss the interest and the limitations of the two models. Sorne weak bands can be attributed to bielectronic transitions. This knowledge of the influence of different structural and electronic parameters which impel the fine structures of the edge and EXAFS spectroscopy are then used to characterise the local structure and stereochemistry of new compounds, of interest for their physical, chemical and catalytic properties. Then we studied:- The structural changes occurring during thermal spin cross-over in iron(ll), iron(lll) and cobalt(ll) complexes. - The stereochemistry of titanium(IV) complexes active in oxidation of sulfides in sulfoxides :at each reaction step, species are octahedral and do not show di µ oxo geometry. - The local order in basket-handle iron porphyrins, model compounds of haemoglobin. The spectrum of the oxy species allows to propose a Fe(ll)-02 formulation rather than a Fe(lll)-02 -. We used the time resolved EXAFS spectrometer at LURE to record structural kinetics data and study iron surroundings during the oxidation of an iron(ll) basket-handle porphyrin
