A diagnostic general-purpose magnetic resonance imaging (MRI) system designed to scan any targeted area of the body (full-body imaging). This system includes a superconducting magnet assembly and can be fixed-location, mobile, or transportable. Some systems can perform MR spectroscopy or various real-time imaging procedures for MRI guided interventional, therapeutic, or surgical applications. The system is available in a variety of system gantry configurations including closed bore, open bore, and open-sided or other kinds of patient accessible designs.
