Public ISBD Titre : Ai-based prediction of entrance surface dose and effective dose in x-ray radiography for patients Type de document : document électronique Auteurs : Souhir Tiaiba, Auteur ; Maroua Madi, Auteur ; Ouassila Boukhenfouf, Directeur de thèse Editeur : Setif:UFA Année de publication : 2025 Importance : 1 vol (53 f.) Format : 29 cm Langues : Anglais (eng) Catégories : Thèses & Mémoires:Physique Mots-clés : Artificial Intelligence (AI) Machine Learning, Effective Dose Entrance Surface Dose Xray Radiography Index. décimale : 530 - Physique Résumé : This thesis focuses on the application of artificial intelligence (AI) in predicting the Effective Dose and the Entrance Surface Dose in X-ray radiography. The aim of this research is to develop an intelligent model capable of accurately estimating radiation doses based on various imaging data, without the need for direct measurements. This contributes to improving radiation protection and reducing risks to patients. The study relies on machine learning algorithms to build a predictive model based on diverse clinical and technical data, including device parameters and examination type. The thesis also presents the fundamental principles of radiation doses, as well as the challenges of medical modeling using artificial intelligence. The proposed model shows promising potential in accurately predicting radiation doses, supporting safer and more efficient clinical decision-making.

Analysis of Radioelements and Heavy Metals Contents in Pesticides by Different Methods: γ Spectrometry, XRF and LIBS / Rayene Ferras

Format : 29 cm Langues : Anglais (eng) Catégories : Thèses & Mémoires:Physique Mots-clés : Analysis of Radioelements XRF and LIBS Index. décimale : 530 - Physique Résumé : This study aims to evaluate the radiological and chemical safety of four commercially available agricultural pesticides (ASTRAD, STORA, STARLIGHT, FLINT) using LIBS, XRF, and gammaray spectroscopy techniques. The results showed that the activity levels of the natural radionuclides (238U and 232Th) were within globally accepted limits, except for ASTRAD, which recorded relatively high activity. LIBS and XRF techniques revealed excessive concentrations of toxic heavy metals such as Ni, Mn, Cu, Cr, and Zn. LIBS was effective in the qualitative detection of elements, including light ones such as C, O, and N, while XRF provided accurate quantitative data on heavy elements. The study recommends strict regulation of pesticide content, full disclosure of their composition, and the adoption of safer alternatives to protect the environment and human health.
