Magnetic resonance imaging apparatus with decreased patient claustrophobia and increased access to patient

摘要

An economic and practical MRI magnet structure defines a patient imaging volume that permits greater access to the patient and reduces patient claustrophobia. The opening of the magnet structure is larger than a central region of the magnet. In one example embodiment, a tubular magnet structure flares out at one or both ends and may approximate a hyperboloid of revolution.
