Methods, systems, software arrangements and storage medium for measuring the magnetic field correlation function ('MFC'), and more particularly, to methods for measuring the magnetic field correlation function utilizing asymmetric spin echoes. Asymmetric Dual Spin Echo Sequences ('ADSE') and Echo Planar Imaging Asymmetric Dual Spin Echo Sequences (&#x201c;EPI-ADSE&#x201d;) may be employed to apply multiple echoes to a sample and acquire data from which the MFC may be determined.

Method, system and software arrangement, for measuring magnetic field correlation

A permanent magnet structure comprising a longitudinally extending flux sce fabricated of magnetically rigid material. The flux source comprises a central cavity with a magnetic field being produced therein. Magnetic dipoles having predetermined magnitude and orientation for compensating nonuniformities in the magnetic field are symmetrically located within the plane of the flux source.

Compensation for magnetic nonuniformities of permanent magnet structures

A phantom for evaluating and calibrating a nuclear magnetic resonance imaging system. The phantom includes a cylindrical housing having a central axis and defining a hollow region therein. The phantom also includes a first conical wall member and a second conical wall member which are congruous to each other and secured to one another at their respective bases. The conical wall members are disposed within and separate the hollow region into a first region outside of the conical wall members and a second region within the conical wall members. The first region is filled with a first predetermined fluid and the second region is filled with a second predetermined fluid. Preferably each conical wall member is symmetrical about central axis and has its apex disposed along the central axis.
