Josset, Anne. "Suivi par thermométrie par imagerie par résonance magnétique (IRM) des ablations thermiques dans les tissus mous". Electronic Thesis or Diss., Strasbourg, 2024. http://www.theses.fr/2024STRAD040.
Texto completo da fonteThermal ablation offers a promising alternative to traditional cancer treatment techniques, particularly due to its minimally invasive feature, which reduces morbidity and side effects. However, it requires the use of appropriate tools for real-time temperature monitoring to attest the effectiveness of the treatment and ensure the safety of the procedure. Magnetic Resonance Imaging (MRI) thermometry is recognized as the gold standard for this purpose, allowing for precise temperature mapping in aqueous tissues using the PRFS (Proton Resonance Frequency Shift) method. Nevertheless, the effectiveness of this method in fat-containing tissues requires careful evaluation. In this thesis, we developed a method to quantify the remaining fat peak signal after various fat suppression methods. This approach was assessed through both in vitro and in vivo experiments. We then evaluated the accuracy of PRFS MRI thermometry with several amounts of fat and different fat suppression methods. Our findings indicate that the residual fat signal impacts PRFS MRI temperature measurements. Consequently, a method was suggested to evaluate temperature variations without fat suppression techniques, using a water/fat separation algorithm. This approach is compatible with real-time sequences and enables accurate measurement of temperature variation in fat-containing tissues

Texto completo da fonteThe occurrence of micropollutants is a major aspect in water quality assessment. For the last few years, analytical methods combining solid-phase extraction, liquid chromatography and tandem mass spectrometry has become the main technique for the analysis of a broad range of micropollutants. On the basis of some pesticides and endocrine disruptor compounds in water analysis, impacts of the parameters: extraction, separation, detection and data processing, on the analysis reliability (repeatability, accuracy, stability, reproducibility…) have been studied. Each step of the analytical method has been optimized and the parameters, affecting substance signals have been discussed. A global reflection upon the cause of signal variations and the possible answers to apply has been conducted. Proposed answers were validated by real matrix analysis and inter-laboratory studies. This work presents the tools and the key-points to ensure the results obtained by liquid chromatography/tandem mass spectrometry analysis

Texto completo da fonteThe lack of potable water is still a problem in many countries. Considering the nearly endless water resource in the oceans, seawater desalination is an increasing attractive solution. Reverse Osmosis (RO) desalination is the main technology used nowadays. However, RO is limited in recovery factor due to the osmotic pressure which increases with salinity. It results high brine volume rejected directly in seawater which induces environmental perturbations. An innovative approach was proposed in the frame of the European project MEDINA in order to reduce these brines: the use of vacuum membrane distillation (VMD) in an integrated RO desalination process. Indeed, VMD allows operating at high salt concentration and can be coupled with solar thermal energy in order to reduce energy requirement. The present work consisted in studying use of VMD for highly salty concentrated waters, both for synthetic and real waters (seawater and RO retentate). An experimental approach was used with a lab-scale pilot plant completed by a theorical approach with a modelling tool. Results show the interest of VMD for the overconcentration of RO retentates. Indeed, VMD can be operated at high salt concentration up to 300 g. L-1 maintaining still high permeate fluxes (7 L. H-1. M-2) and nearly pure permeate (salt rejection of 99. 96 %). Brine volumes can so be reduced by 5 and recovery factor increased up to nearly 90 %. Fouling (organic, scaling or bio-fouling) is limited. Salt crystal deposit has been observed and analysed. Precipitation mechanisms have been proposed, mainly with the crucial part of the calcium. VMD coupling with solar thermal technologies allow an important reduction of the energy requirement. Use of salinity gradient solar ponds and solar thermal collectors have been compared and have shown the potentialities of using solar thermal collector in order to obtain high temperatures and so high permeate fluxes
