Zpracování výukového programu pro předměty: "DOZIMETRIE IONIZUJÍCÍHO ZÁŘENÍ" "KLINICKÁ DOZIMETRIE" / Processing of education schedule the areas: "Dosimetry of ionising radiation", "Clinical dosimetry"

LEŠTINA, Štěpán January 2007 (has links)
The problem I am dealing with in the diploma thesis : Processing of education schedule the areas: {\clqq}Dosimetry of ionising radiation``, {\clqq}Clinical dosimetry``, is connected with a creating of practical internet applications of formal training of university´s students. To design certain applications which would tend to be more effective in teaching and would lead to easier understading of given curriculum is the main aim of this work. It also concerns a didactic approach to teaching the subjects, such as: {\clqq}Dosimetry of ionising radiation``, {\clqq}Clinical dosimetry``, which is included in curriculum of Bachelor and Master degree studies in the Department of Radiology and Toxicology at University of South Bohemia České Budějovice. The important component of the thesis is a teaching program which is accesible also on the web side : http://www.lestinas.webzdarma.cz

Multi-scale dosimetry for targeted radionuclide therapy optimisation / Dosimétrie multi-échelle pour l'optimisation de la radiothérapie interne vectorisée

Marcatili, Sara 20 October 2015 (has links)
La Radiothérapie Interne Vectorisée (RIV) consiste à détruire des cibles tumorales en utilisant des vecteurs radiomarqués (radiopharmaceutiques) qui se lient sélectivement à des cellules tumorales. Dans un contexte d'optimisation de la RIV, une meilleure détermination du dépôt d'énergie dans les tissues biologiques est primordiale pour la définition d'une relation dose absorbée - effet biologique et pour l'optimisation des traitement du cancer. Cela nécessite une évaluation quantitative de la distribution de l'activité (avec la technique d'imagerie moléculaire la plus appropriée) et d'effectuer le transport du rayonnement à l'échelle à laquelle se produisent les phénomènes biologiques pertinents. Les méthodologies à appliquer et les problématiques à établir dépendent strictement de l'échelle (cellule, tissu, organe) de l'application considérée, et du type de rayonnement en cause (photons, électrons, particules alpha). Mon travail de recherche a consisté à développer des techniques dosimétriques dédiées (dosimétrie mono-échelle) et innovantes, capables de prendre en compte la particularité de différents scénarios expérimentaux (cellulaire, pré-clinique, RIV clinique). / Targeted Radionuclide Therapy (TRT) consists in killing tumour targets by using radiolabeled vectors (radiopharmaceuticals) that selectively bind to tumour cells. In a context of TRT optimization, a better determination of energy deposition within biologic material is a prerequisite to the definition of the absorbed dose-effect relationship and the improvement of future cancer treatment. This requires being able to quantitatively assess activity distribution (with the most appropriate molecular imaging technique) and perform radiation transport at the scale at which biologically relevant phenomena occur. The methodologies that should be applied and the problematic to be faced strictly depend on the scale (cell, tissue, body) of the application considered, and on the type of radiation involved (photons, electrons, alpha). This research work consisted in developing dedicated dosimetric techniques (single-scale dosimetry) capable of taking into account the peculiarity of different experimental scenarios (cellular, pre-clinical, clinical TRT).
