  • Patent number: 8710843
    Abstract: A magnetic resonance imaging (MRI) apparatus suitable for radiotherapy. The apparatus includes two sets of coil pairs, each coil pair forming a Maxwell-like coil. The two sets of coil pairs share a common transverse plane, have opposing polarities, and define a common plane of symmetry and an imaging area. The two sets generate a substantially homogenous electromagnetic field in a first transverse direction in the imaging area and peripheral electromagnetic fields in a direction opposite to the first transverse direction in a peripheral area. The apparatus also includes at least one focusing magnet positioned in the peripheral areas to generate a focusing electromagnetic field in a focusing area, in a direction substantially the same as the first transverse direction. At least a portion of the peripheral electromagnetic fields is maintained in a defocusing area between the focusing area and the imaging area.
