Mobile unilateral magnets have been developed in the past ten years to investigate samples that cannot be moved or do not fit within the bore of traditional MRI scanners. We have designed a novel device based on an elliptical magnet with a large free space at the centre of the magnet to host the entire coil system and, eventually, other sensor for multimodal studies. The magnet generates a magnetic field parallel to its surface and has been optimized to have a highly homogeneous B0 along the ellipse major axis to allow 1D imaging along such direction. The maximum field intensity B0=124 mT is reached at 7 mm distance from the surface magnet. We present a complete coils system, receiver rf and gradient coil.
