It shows that volume of the coil of the multiple block co-polymer chain increases with the interaction energy of the two components, especially in the direction of the long axis, so that the coil is stretched. 结果表明,多嵌段高分子链线团的体积随两组分相互作用能的增加而膨胀,主要在长轴方向上使线团形状变长。
In parallel imaging, spatial encoding using multiple coils partially replaces the spatial encoding normally accomplished using gradients, because additional information is obtained from the spatial variation in the coil sensitivity profiles. 而在并行成像中,空间编码通过使用多线圈部分地代替了通常使用的梯度编码方式,因为格外的一些空间信息可以通过多线圈之间的线圈敏感度差异来获得。
The parallel MRSI applies multiple coil array for parallel data acquisition, which reduce the acquisition time by reduce the phase encoding steps in one or two directions in space. 新近出现的并行MRSI技术采用多个接收线圈阵列同时采集数据,在保持空间分辨率不衰减的情况下,从一个或两个空间方向减少相位编码步数,大大减少了扫描时间。
