keyboard scan reference program 键盘扫描参考程序
A software method based on the reference scan is proposed for MRI phase artifact correction. Firstly,the reference scan without frequency encoding gradient and phase encoding gradient is executed,and an echo train is acquired.
基于参考扫描原理提出了一种MRI(Magnetic resonance imaging)相位伪影的软件校正方法,首先进行一次不加频率编码梯度和相位编码梯度的参考扫描,将获得的回波链数据沿频率编码方向做傅里叶变换后求出各回波间的相位误差,由此建立相位误差补偿矩阵,对K空间数据进行校正,最后重建得到伪影校正后的图像。

SENSE reconstruction algorithms can unfold the superposed voxels and combine into a full FOV image by the calculation of the coil sensitivity with the body coil reference scan data.
SENSE 重建算法通过计算重叠位置的线圈灵敏度系数，将多个线圈得到的有重叠伪影的图像进行展开，得到一幅全-FOV 的无重叠的图像。
After a scan lasting a minute, Mr Blankfein said he found the reference on page five, which seemed to surprise Mr Dowd.
扫视了一分钟后，贝兰克梵说他在第五页上找了前述内容，这似乎让多德颇感吃惊。
It can also be used as reference to improve efficiency of communication by avoiding unnecessary waste and to scan the whole media policy renewedly.
这对于减少不必要的损耗，提高传播的有效率，重新审视现行的媒介政策，亦是一种有意义的借鉴。
