The system can include a plurality of magnetic segments and/or a plurality of ferromagnetic segments. Each magnetic segment can be positioned adjacent to at least one of the plurality of magnetic segments. Each ferromagnetic segment can be positioned adjacent to at least one of the plurality of magnetic segments. In various embodiments, a size, shape, positioning and/or number of magnetic segments and/or ferromagnetic segments in the system, as well as a magnetization direction of the magnetic segments can be predetermined based on, for example, predetermined parameters of the system (e.g., a desired magnetic field strength, direction and/or uniformity of the magnetic field, a desired elimination of a magnetic fringe field and/or total weight of the system) and/or based on a desired application of the system (e.g., performing a magnetic resonance imaging of at least a portion of a patient and/or performing a magnetic resonance spectroscopy of a sample).

Abstract: An MRI image is generated base on a first MRI scan and a second MRI scan. Using corresponding first and second k-space grid data, at least one instance of subject movement during acquisition of scan line data as part of the first MRI scan or second MRI scan is identified. Motion sensor data is consulted to determine if each identified instance of subject movement was during the first MRI scan or the second MRI scan. Corrected k-space grid data is generated using the other k-space grid data on a scan line by scan line basis and a resulting MRI image is generated therefrom.
