ABSTRACT:
An MRI system has a magnet configuration that provides access for a surgeon or other personnel to perform procedures on a patient under support of real time MRI image. The magnet system uses a plurality of C-shape solenoidal magnets oriented to form an imaging volume in a central region of the magnets so that the magnetic flux from each magnet contributes to the magnetic field in the imaging volume. The configuration provides a high strength field in the imaging volume. The MRI system has a gradient coil for providing a magnetic field gradient in the imaging volume and an Rf coil for providing an Rf signal in the imaging volume. Preferably, the Rf coil also receives NMR signals from a specimen in the imaging volume.
