Résumé :

Il lavoro presentato in questa tesi si concentra sullo sviluppo e sul miglioramento della strumentazione e dei metodi applicati all'imaging a trasmissione di neutroni. Le attività di ricerca sono state svolte presso il laboratorio di "Imaging and Materials Science and Engineering" (IMAT). Questa struttura fa parte della sorgente di neutroni ISIS presso il Rutherford Appleton Laboratory (UK). I neutroni qui sono prodotti dalla spallazione di un bersaglio di tungsteno colpito da protoni con energia di 800 MeV. I neutroni risultanti vengono moderati e convogliati attraverso le guide dei fasci ver

Résumé :

Introduction The optimal condition for skeletal muscle function is represented by an efficient activation of processes that regulate muscle development, growth, regeneration and metabolism. When the balance among these events is missing, a pathological condition arise. In particular, loss or decrease of skeletal muscle function and mass is linked with severe health diseases such as muscle dystrophies, cancer, obesity and aging process. In this context, sarcopenic obesity, a metabolic disorder followed by atrophy of muscle fibres and reduction of stem cell reservoir (satellite cells in musc

Résumé :

For more than 50 years attening filters have been inserted into the beam path oflinacs to produce a uniform energy fluence distribution of the photon beam and make it suitable for clinical use. Recently, linacs without flattening fifilter (Flattening FilterFree - FFF) are increasingly used in radiotherapy because of its benefifits, e.g. high dose rate (2000 MU/min), reduced scattered and leakage radiation. Hypofractionated radiotherapy is interested in the high dose rate of FFF beams to shorten the treatment delivery time (TDT) especially the FFF beams have acceptable flatness at small fif

Résumé :

This thesis seeks to study in depth the influence of Imam al-Juwayni on Imam al-Ghazali's discussion of theology and whether or not the latter's ideas are properly derived from the former. The first chapter deals with an analysis of the life of both the Imams against the background of the religious milieu of their time. The second chapter discuss the views of the two Imams on Ilm al-Kalam. The third chapter attempts to compare and contrast Imam al-Juwayni's and Imam al- Ghazali's approach to the doctrine of the origin of the world and the existence of God.

International development policies and practices are curiously silent on the subject of religion. It is an overt silence, in the sense that religion appears to be deliberately omitted from consideration. There is an implicit assumption that societies in the South will adopt the secular project of political modernity already perfected in and by the North. The paradox, however, as my dissertation demonstrates, is that development and religion are deeply imbricated at various local, national and transnational sites of power-knowledge.

A cylindrical shaped target volume, with an organ at risk inside, was defined in MasterPlan to evaluate the dose distribution modeled by the PBE algorithm.

In this project, ion chamber measurement and film dosimetry were used to verify dose distributions for a new stereotactic IMRT (Intensity Modulated Radiation Therapy) treatment planning system. This technique combines the principles of stereotactic radiosurgery and IMRT to significantly increase the positioning accuracy compared with conventional IMRT . Ion chamber measurements reveal that the discrepancy between the measured and the calculated dose at the isocenter can be up to 2%. Angular dependence of ion chamber sensitivity and the tissue equivalence of the phantom material were determined

It is standard practice in radiation therapy to have two independent calculations for the number of monitor units used in patient treatment plans. The relationship between monitor units and absorbed dose to water is sophisticated for MLC-based IMRT.

Résumé :

In this thesis, the use of inhomogeneity corrections in intensity modulated radiotherapy (IMRT) inverse treatment planning is investigated. Firstly, the dosimetric consequences of CT beam hardening artifacts present on images used for treatment planning are estimated and found to be of little clinical significance (<1% dose difference). Secondly, experiments to evaluate the PEREGRINE Monte Carlo system (Nomos, Cranberry, PA) are undertaken for a 6 MV photon beam. The use of inhomogeneity corrections in clinical treatment planning is assessed for five clinical head and neck cancer cases.

Résumé :

Techniki dynamiczne IMRT i VMAT umożliwiają bardzo precyzyjne modulowanie rozkładu dawki w objętości guza nowotworowego przy jednoczesnym oszczędzaniu tkanek zdrowych - struktur krytycznych. Z jednej strony dysponujemy bardzo precyzyjnym systemem planowania rozkładu dawki, z drugiej za realizację planu odpowiada aparat terapeutyczny, który „obarczony” jest tolerancją działania: mechaniczną i elektroniczną. Konieczna jest zatem weryfikacja zgodności rozkładu dawki zaplanowanego ze zrealizowanym - rzeczywistym. W radioterapii każdy plan leczenia musi być zweryfikowany, czy to przed realizacją

Résumé :

Die fraktionierte stereotaktisch geführte Radiotherapie stellt eine Möglichkeit der Behandlung intrakranieller Tumoren dar, bei denen eine chirurgische Resektion nicht oder nicht vollständig möglich ist. Ziel dieser Arbeit war der Vergleich der Dosisverteilung von Bestrahlungsplänen, die mittels fluenzmodulierter (IMRT) und 3D konformaler stereotaktisch geführter Bestrahlungstechnik (conformal beam) für Hypophysenadenome und petroclivale Meningeome erstellt wurden. Auf Basis des CT-Datensatzes eines Alderson-Phantoms erfolgten zunächst die systematische Untersuchung der IMRT Eingabeparameter u
