Magnetic resonance imaging (MRI) is a medical imaging modality with a strong potential for application of metamaterials as the signal bandwidth is very limited. However, MRI physicists are not experienced in the field of metamaterials and metamaterials researchers are not experienced in the field of MRI. Our visit is aimed at bridging this gap and explore the opportunities that metamaterials can offer to the MR imaging community. In this framework, we will give a presentation that gives a basic introduction into MR physics with focus on its EM principles and presents some of our research on new radiofrequency development in ultra high field MRI. The static magnetic field strength for clinical MRI systems is typically 1.5 and 3 Tesla. In our institute we have an experimental 7 Tesla system available allowing images with higher resolution and image quality. However, the high magnetic field has also introduced severe challenges related to the radiofrequency field required for signal induction. This arises from the increased RF operating frequency (300 MHz) at 7 Tesla causing the RF wavelength in tissue to become smaller than anatomical dimensions. This has made radiofrequency technology an intense and crucial research topic in Ultra high field MRI. New research opportunities arise from the fact that the classical near field coupling used in the MRI community to apply an RF field is suboptimal at these high frequency and antenna arrays are needed to realize optimal penetration of the RF signals into the body. We will present our recent work on the development of RF antenna arrays for MRI of the body at 7 Tesla. Initial images of the heart, kidneys and prostate have a promisingly good image quality. However, since the designs are preliminary, further improvement is expected and metamaterials may well play an important role in optimizing these antenna arrays.
