Sviluppo ed ottimizzazione di un sistema di dose-tracking applicato alle strutture radiologiche dell'area Torino Ovest

In this study I investigated all the aspects concerning the acceptation, optimization and development of Gray Detector, that is a dose-tracking system used in radiological facilities located within the wide area of West Turin. The thesis is divided in three parts. First of all, I gave an illustration of all the preliminary concepts needed for the reading of the text. More specifically, I explained the principles of working of all treated devices and the related dosimetric quantities, the current and future legislation inherent the management of the dose and the general features of a Dose Management System. In second part, I illustrated the work performed in order to make the software accepted. I described all the modifications done with the purpose of making the software trustworthy for what concerns patient's dose monitoring at Azienda Ospedaliera Ordine Mauriziano, ASL TO3 and ASL Città di Torino. Also, I gave a description of the software. At the end, I yield a brief explanation of the quality control of radiological devices. In third part I studied some applications of the software at Azienda Ospedaliera Ordine Mauriziano. More deeply, I investigated three fields. First, I examined the Effective Dose linked with all the studied examinations which are performed in the facility, namely Angiography, Computed Tomography and Mammography. Then, I used the software to compare dosimetric indexes linked to distinct devices but used for the same scopes. Secondly, I carried on a comparison between Diagnostic Reference Levels and dosimetric quantities given by Gray Detector. Thirdly, under the light of future application of European Directive 59/13/EURATOM, I simulated the process of classification of patients' exposure indexes as well as tried to create a quantity useful to directly link the dosimetric values provided by Gray Detector to Effective Dose in all procedures (Angiography, Computed Tomography and Mammography).
