Het doel van deze eindverhandeling bestond erin om een phased array van oppervlaktespoelen voor MRI te bestuderen, simuleren en ontwikkelen. Simulatie door middel van de Finite Difference - Time Domain methode (FDTD) wordt besproken, en een methode om geconcentreerde elementen te combineren met een niet reflecterende simulatie grenszone (PML) werd opgesteld. De benodigdheden om zo'n array te bouwen worden besproken en de beperkingen geanalyseerd vanuit meerdere standpunten, zoals veiligheid en kostprijs. De oplossing voor enkele courante problemen zoals ontkoppeling tussen spoelen en mantelstromen wordt beschreven. Ook wordt theoretisch een opstelling besproken voor beeldvorming met Xenon-129, samen met enkele technieken om de prestaties te meten zonder een MRI scanner beschikbaar te hebben. The goal of this thesis was the analysis, simulation and development of a phased array of surface coils for MRI. Simulation using the Finite Difference - Time Domain method is analysed, and a method to combine a perfectly matched layer (PML) with lumped elements is introduced. The requirements for an array and the practical limitations are analysed from several perspectives, such as safety and cost. The solution to several common problems, like decoupling between coils and common-mode currents, are described. Finally a theoretical array for imaging using Xenon-129 was proposed together with techniques to test it without having an MRI scanner available.

This Third Edition of Essentials of Nuclear Medicine Physics and Instrumentation expands the finely developed illustrated review and introductory guide to nuclear medicine physics and instrumentation. Along with simple, progressive, highly illustrated topics, the authors present nuclear medicine-related physics and engineering concepts clearly and concisely. Included in the text are introductory chapters on relevant atomic structure, methods of radionuclide production, and the interaction of radiation with matter. Further, the text discusses the basic function of the components of scintillation and non-scintillation detector systems. An information technology section discusses PACs and DICOM. There is extensive coverage of quality control procedures, followed by updated chapters on radiation safety practices, radiation biology, and management of radiation accident victims.
