Dans le cadre de la réalisation de ce mémoire sur « le développement durable », l’équipe des centres imagerie ELSAN Var-Gard (Toulon/Nîmes) a accepté de faire un état des lieux de leurs pratiques sur 7 sites, équipés de Scanners2 et IRM3, afin de dégager des axes d’amélioration et déployer de nouvelles méthodes de travail. Après la constitution de ...
Artificial intelligence (AI) solutions are revolutionizing radiology workflow, from image acquisition to diagnosis. Among these solutions, deep learning models achieve increasingly accurate performance and compete with clinicians on some medical imaging problems. These solutions aim to evolve the radiologists' practice by providing them with additi...
Decomposition of digital images into other basis or dictionaries than time or space domains is a very common and effective approach in image processing and analysis. Such a decomposition is commonly obtained using fixed transformations (e.g., Fourier or wavelet) or dictionaries learned from example databases or from the signal or image itself. In r...
Four-dimensional (4D) computed tomography (CT) images are used for the radiotherapy planning of thoracic and upper-abdominal tumors to account for breathing motion. It assumes that the breathing cycle is periodic which is often not the case, especially for patients suffering from respiratory diseases, resulting in artifacts in tomographic images wh...
This research project is expected to be financed by a CIFRE scholarship in collaboration between GE Healthcare and CentraleSupelec. We are seeking to predict Major Adverse Cardiovascular Events (MACE). These are typically embolism and aneurisms in the aorta and the coronary arteries, that give rise respectively to interrupted blood flow to the hear...
The purpose of tomography is to reconstruct a volume from its projections. In Computed Tomography (CT), X-rays are transmitted to a patient and attenuated by their tissues: the projections are obtained from the measured attenuation. For Positron Emission Tomography (PET), a radionuclide injected inside a patient emits a positron that generates two ...

Assess the feasibility of a randomized controlled trial (RCT) exploring the use of medical imaging as a therapeutic education (TPE) intervention in external radiation therapy. Experimental feasibility trial of "RCT" type carried out in a single-center, between November 2019 and March 2020, following adult patients treated by thoracic radiotherapy. ...
Magnetic resonance imaging (MRI) allows for the non-invasive study of metabolism in soft tissues. This thesis consists in the development of innovative methods for metabolic cerebral imaging using sodium (²³Na) and phosphorus (³¹P) MRI at ultra-high magnetic field (UHF). These nuclei are of interest because of the central roles of their electrolyte...
Le bruxisme est un phénomène répandu qui peut se caractériser par des contacts dentaires inter-arcades. Les forces exercées par un patient bruxeur peuvent être jusqu’à trois fois supérieure à l’activité fonctionnelle de l’appareil manducateur et vont être transmises aux dents ainsi qu’au parodonte. Ce travail s’est intéressé plus particulièrement à...
