| titleOfInvention | Magnetic assembly for nuclear magnetic resonance comprising a halbach-type cylindrical ring |
| abstract | The present invention identifies construction methods and techniques for obtaining the field homogeneity magnetic field required for Magnetic Resonance Imaging (MRI), on the order of 20ppm in the region of interest (the term "shimming" will be used hereinafter to refer to such techniques). The method of construction is characterized by obtaining a homogeneous field region for MRI analysis having a linear dimension equal to about 40% of the linear dimension of the magnet. Shimming techniques involve the use of processed magnetic materials and, while using materials that inherently have a large distribution of magnetization values, can also accurately control the magnetization of the correction elements. The result is a lightweight, small magnet suitable for magnetic resonance imaging for specialized clinical applications such as peripheral joint analysis, eye analysis, and veterinary applications. |
