Section thickness in two-dimensional Fourier transform (FT) imaging is dependent on gradient strength and the shape of the radio-frequency pulses used to excite the nuclei. By manipulation of these parameters, it is possible to obtain 2.5-mm-thick sections in contiguous, multisection imaging. Because this method is efficient in imaging with long repetition times (TR), it effectively complements three-dimensional FT thin-section imaging techniques, which require imaging with short TRs. Fifteen double-echo, contiguous images of 0.9 X 0.9 X 2.5-mm resolution were obtained in 17.1 minutes for a TR of 2 seconds.
二维傅里叶变换（FT）成像中的层面厚度取决于梯度强度以及用于激发原子核的射频脉冲的形状。通过对这些参数的操控，在连续多层面成像中有可能获得2.5毫米厚的层面。由于该方法在长重复时间（TR）成像时效率较高，它有效地补充了三维FT薄层成像技术，后者需要短TR成像。对于2秒的TR，在17.1分钟内获得了15幅分辨率为0.9×0.9×2.5毫米的双回波连续图像。
