摘要： In a method and magnetic resonance (MR) apparatus for heart diffusion imaging, when an ECG trigger signal by a computer that operates an MR scanner, the MR scanner is operated to acquire a navigator echo before a stimulated echo sequence, in order to detect diaphragm position information. When the first diaphragm position information is not located in an acquisition window, the stimulated echo sequence is not executed, and the computer waits to receive the next ECG trigger signal. The detection time of the navigator echo after the stimulated echo sequence as well as the acquisition time of the stimulated echo sequence, are thus eliminated when the first diaphragm position information does not meet requirements, so can significantly reduce scanning time, and increase the image SNR.

摘要： In a magnetic resonance coil selection method and selection computer, a range parameter of a target region (ROI) to be detected is acquired, and a detection range parameter of each available coil is acquired. A coil having a detection range that overlaps with a range of the ROI is determined and then selected. The selected coil is then used in the operation of a magnetic resonance scanner to acquire magnetic resonance data. The SNR of the magnetic resonance scanner is thereby increased, so as to improve the imaging quality.

摘要： In a multi-slice data acquisition method and device and a magnetic resonance imaging method and apparatus, a number NC of fractional acquisitions and a number NS of slice individual, complete data acquisition of the multi-slice data acquisition are determined. Using an iterative odd/even arranging method, a slice data acquisition order of each of the fractional acquisitions is arranged according to an ideal number of iterations. The ideal number of iterations is obtained from multiple undetermined numbers j of iterations of the iterative odd/even arranging method according to the number NS of slice data and the number NC of fractional acquisitions. This multi-slice data acquisition method optimizes the slice data acquisition order so as to significantly reduce the effect of magnetization transfer and crosstalk.

摘要翻译： 在多切片数据采集方法和装置以及磁共振成像方法和装置中，确定了多片数据采集的数字NC分数采集和数量NS的切片个体，完成数据采集。 使用迭代奇/偶布置方法，根据理想的迭代次数来布置每个分数获取的切片数据采集顺序。 从迭代次数奇数/偶数排列方法的多个未确定数量j可以得到理想的迭代次数，根据切片数据的NS数量和分数获取的数目NC。 这种多切片数据采集方法优化了切片数据采集顺序，以显着降低磁化传递和串扰的影响。
