    • The present invention provides a system and method for on-the-fly optimization of the timing of suppression pulses and a k-space filling scheme for user-prescribed imaging parameters. The invention also minimizes total data acquisition time for the sequence tailored to the particular user-prescribed imaging parameters. A pulse sequence uses a 180° pulse to invert the magnetization corresponding to the suppressed tissue so that a maximum amount of time is provided to play out alpha or imaging pulses after each inversion. The pulse sequence optimizes the number of alpha pulses played out after each inversion pulse based on a specific protocol or imaging parameters selected by the user. This pulse sequence allows for a modified k-space filling scheme that places, at the center of k-space, the echo that most closely corresponds to the null point of the suppressed tissue. For the first inversion pulse, a flip angle less than 180° is used to drive the suppressed tissue magnetization into a steady-state condition immediately.
    • 本发明提供了一种用于对用户规定的成像参数进行抑制脉冲定时的实时优化和k空间填充方案的系统和方法。 本发明还使针对特定用户规定的成像参数的序列的总数据获取时间最小化。 脉冲序列使用180°脉冲来反转对应于抑制组织的磁化,使得在每次反转之后提供最大量的时间以播放α或成像脉冲。 脉冲序列基于用户选择的特定协议或成像参数来优化每个反转脉冲之后播放的α脉冲数。 该脉冲序列允许修改的k空间填充方案,其在k空间的中心放置与抑制组织的零点最接近的回波。 对于第一反转脉冲,使用小于180°的翻转角来立即将抑制的组织磁化驱动到稳态条件。
