摘要： In a magnetic resonance imaging method and apparatus, navigation data are collected in a navigation acquisition timeslot of a scanning sequence. A determination as to whether to accept or reject echo data that are subsequently collected in multiple echo acquisition timeslots is made. If the phase relationship of the navigation data and the reference data in k-space is greater than or equal to the reference value, the collected echo data are accepted and if the aforementioned phase in k-space is less than the reference value, the collected echo data will be rejected, and sequential scanning will be performed again, and the navigation data again will be collected using the navigation acquisition timeslot, and the aforementioned determination is repeated.

摘要： In an imaging method and device for water/fat separation in MRI using a two-point Dixon FSE sequence, each refocusing RF pulse corresponds to two readout gradients of the same polarity, each being center-divided into a smaller rear part and a larger front part, and one rephasing gradient of opposite polarity. In running the FSE sequence, each echo signal acquired is subjected to an FFT, to reconstruct an image with water and fat in phase and an image with water and fat in opposed phases. Data of each echo signal are subjected to a partial Fourier transform; and the in-phase water/fat image and the opposite-phase water/fat image are subjected to a water/fat separation algorithm, to obtain a pure water image and a pure fat image.

摘要： In an RF excitation method and device for a magnetic resonance imaging system, the RF pulses are emitted in a STEAM sequence, the STEAM sequence including, in time order, a first 90-degree excitation pulse, a second 90-degree excitation pulse and a third 90-degree excitation pulse. Gradient pulses are activated that act in cooperation with the STEAM sequence, the gradient pulses including, in time order, a first gradient pulse, a second gradient pulse and a third gradient pulse. Each of the gradient pulses is activated simultaneously with the corresponding RF pulse. The direction of each of the gradient pulses is the vector sum of multiple gradient pulses in different directions, the directions of any two of the gradient pulses being the same and intersecting with the direction of another of the gradient pulses.
