    • In an examination method and apparatus utilizing nuclear magnetic resonance, high frequency pulses for producing nuclear magnetic resonance are applied by successively imposing a first 90.degree. pulse, a first 180.degree. pulse, a second 90.degree. pulse, and a second 180.degree. pulse substantially immediately after the second 90.degree. pulse, and a next pulse sequence is initiated upon elapse of a wait time after the second 180.degree. pulse has been applied. The wait time is rendered much shorter than the conventional prior art wait times for high speed scanning operation, by forcibly aligning magnetization M first with the direction of a -Z direction axis and then with the direction of a +Z direction axis, using the second 90.degree. pulse and the second 180.degree. pulse. By applying a number of first 180.degree. pulses, a number of nuclear magentic resonance signals are produced for additionally shortening the overall measurement time.
    • 在使用核磁共振的检查方法和装置中,通过依次施加第一个90°脉冲,第一个180°脉冲,第二个90°脉冲和第二个180°脉冲,基本上立即产生用于产生核磁共振的高频脉冲 在第二个90度脉冲之后,并且在施加第二个180度脉冲之后经过等待时间后开始下一个脉冲序列。 通过将磁化M首先与-Z方向轴的方向,然后与+ Z方向轴的方向强制对准,等待时间比传统现有技术的高速扫描操作等待时间短得多,使用第二个 90度脉冲和第二个180度脉冲。 通过应用多个第一180度脉冲,产生许多核磁共振信号以额外缩短整个测量时间。
