摘要： For isotropic diffusion weighting during magnetic resonance imaging, a motion-probing magnetic field gradient pattern is manufactured from a template by searching for an optimum value of a skew parameter (ε) of the template. The gradient pattern includes a first pattern before at least one RF refocusing pulse and a second pattern after the refocusing pulse in which the second pattern is symmetrical with the first pattern. For example, gradient coils produce a respective gradient component along each of three orthogonal directions, and for each component and each pattern, the gradient pattern has one cycle of opposite polarity lobes about a crossing point, and for each pattern, the crossing point of the cycle in one of the orthogonal directions is a midpoint of the cycle; and the skew parameter (ε) specifies a difference in time between the crossing points of the cycles in the other orthogonal directions.

摘要： A system has been developed for mapping the magnetic field during a balanced steady-state free precession (SSFP) sequence. Field maps are generated by analyzing the magnitude of images acquired using the SSFP imaging sequences with phase increment or frequency shift. The system maps the magnetic field relevant to the imaging sequence and need not rely on phase information. The field maps may be applied to adjust the hardware for correcting the field anomalies contained in the maps. The field maps may also be used for separation of water and fat signals in SSFP imaging.
