1) Truncation artifact
截断伪影
1.
However,this results in truncation artifacts in the image.
在磁共振成像(MRI)中,为了缩短成像时间并使图像保持较高的信噪比,往往只采集部分相位编码的磁共振信号进行图像重建,但在重建的图像上会出现截断伪影。
2.
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。

补充资料：部分容积效应伪影
部分容积效应伪影
超声学术语。声束宽度在非聚焦区可达几毫米至1cm以上，当其遇到小于声束切面厚度的病灶时，在声像图上出现病灶区与其周围区回声相互重叠的图像而造成的伪影。这可导致例如小囊肿内部存在有细小光点而误认为实质性肿物的分析错误。
