CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA design procedure for radio frequency (RF) coils to be used in magnetic resonance imaging (MRI) applications is presented. The analysis is carried out by resorting to a full-wave numerical code based on the method of moments (MoM). Indeed, at the increasing of the operating frequency quasi-static solutions are no longer valid and more accurate electromagnetic tools are needed. The optimization is based on an iterative procedure that has been implemented by using a genetic algorithm (GA). The GA is used to determine the geometry of the coil by imposing the homogeneity of the RF magnetic field amplitude in a volume inside the coil at the resonance frequency. Some preliminary numerical results have been obtained for a volume coil with cylindrical shape and resonating at 190 MHz
