While the predominant MR market share is taken up with high-field systems (1.0T and above), there are benefits to imaging at mid-field. Mid-field systems can have a compact fringe field, low weight, compact design facilitating siting, low susceptibility-based geometric distortion and reduced RF heating with or without the presence of implants. Mid-field systems have historically been associated with sub-par image quality due to lower signal-to-noise behavior coupled with an absence of state-of-the-art hardware. Here we present a head-only, superconducting mid-field system designed with high-performance system components aimed at achieving comparable image quality to typical 1.5T systems in comparable scan times.
