The method for cutting down imaging time used usually in clinical application is called segmented K-space imaging.

为了缩短成像时间，常常采用部分K空间成像技术。

Sampling segmented K-space data makes a truncation of MR signal which is with continuous frequencies, leads to the truncation artifact in the reconstruction images after Fourier transform.

由于采集部分K空间数据成像是对连续频率MR信号的截断，导致经过傅立叶变换后的重建图像中出现截断伪影。
