This project aims to develop a new type of radiofrequency coil array to ensure high-field magnetic resonance imaging (MRI), with all its benefits, is available for a broader range of applications. High-field MRI offers faster scans with more detailed images than lower field systems. This enhanced sensitivity potentially enables smaller structures to be resolved in the body. At high fields, however, standard radiofrequency coils, an essential component of MRI systems, can distort images and induce potentially harmful tissue heating. The aim is to design and develop a rotating multi-channel radiofrequency coil array, with dedicated image reconstruction software, to overcome these limitations. This would facilitate detailed images that can be obtained quickly and safely.Read moreRead less
