A new 2D single-shot imaging technique is introduced that uses only one dimension of Fourier encoding. The second dimension is encoded in time, rather than using phase encoding. The data is acquired in the form of a closely spaced echo train with each echo produced from a different physical line in the object. A 1D Fourier transform is applied to each echo for image reconstruction. Because only the desired lines are excited, there can be no aliasing in the time encoding direction even when the object is much larger than the field of view. This technique is also very insensitive to motion, as motion-related artifacts do not propagate in the time encoding direction.
介绍了一种新的二维单次成像技术，该技术仅使用傅里叶编码的一个维度。第二个维度在时间上进行编码，而不是使用相位编码。数据以紧密间隔的回波链形式采集，每个回波由物体中不同的物理线产生。对每个回波应用一维傅里叶变换进行图像重建。由于仅激发所需的线，即使物体比视野大得多，在时间编码方向上也不会出现混叠。该技术对运动也非常不敏感，因为与运动相关的伪影不会在时间编码方向上传播。
