Recently, we introduced a new numerical approach to the design and optimization of NMR selective pulses, which we have christened "SPINCALC" (J. T. Ngo and P. G. Morris, Biochem. Soc. Trans. 14, 1271 (1986); J. T. Ngo and P. G. Morris, Magn. Reson. Med. 5, 217 (1987]. The first practical application of pulses generated by SPINCALC is demonstrated on a standard 0.5-T clinical MRI system. Results are shown for single phase pi pulses suitable both for selective inversion and for selective refocusing. The extension of SPINCALC to multidimensional pulses is illustrated by the design of a two-dimensional pi pulse.
最近，我们引入了一种用于核磁共振（NMR）选择性脉冲设计与优化的新数值方法，我们将其命名为“SPINCALC”（J. T. Ngo和P. G. Morris，《生物化学学会会刊》14，1271（1986）；J. T. Ngo和P. G. Morris，《磁共振医学》5，217（1987））。在一台标准的0.5-T临床磁共振成像（MRI）系统上展示了由SPINCALC生成的脉冲的首次实际应用。给出了适用于选择性反转和选择性重聚焦的单相π脉冲的结果。二维π脉冲的设计说明了SPINCALC向多维脉冲的扩展。
