Nuclear magnetic resonance imaging (MRI) is a diagnostic technique that collects, analyzes and processes anatomical images in a very detailed manner through the use of magnetic fields.

In particolare, questo elaborato approfondisce il principio di funzionamento della suddetta tecnologia dal punto di vista elettro-fisico, la formazione dell’immagine derivante, dovuta principalmente alla sovrapposizione di più gradienti, e la componentistica della strumentazione. Infine, vengono esaminati alcuni vantaggi e svantaggi nell’utilizzo di questa tecnica e viene presentato un esempio di sistema integrato: la risonanza magnetica nucleare (MRI) utilizzata assieme alla tomografia a emissione di positroni (PET).

Abstract
Nuclear magnetic resonance imaging (MRI) is a diagnostic technique that collects, analyzes and processes anatomical images in a very detailed manner through the use of magnetic fields. It is mainly used in the medical field, with the aim of facilitating the diagnosis of anomalies present within the human body, which are not always clearly definable using other techniques. In particular, this paper delves into the operating principle of the aforementioned technology from an electro-physical point of view, the formation of the resulting image, mainly due to the superposition of multiple gradients, and the components of the instrumentation. Finally, some advantages and disadvantages in using this technique are examined and an example of an integrated system is presented: nuclear magnetic resonance (MRI) used together with positron emission tomography (PET).File | Dimensione | Formato | |
