Therefore, the scanningperiod is shortened, the scanning frequency and system accuracy are enhanced and the data acquisition reliability is enhanced compared with the prior art.
从而缩短扫描周期，加快扫描频率并提高系统精确度，相对于现有技术使数据采集的可靠性提高。

By scanning the boys twice the scientists were able to create a detailed picture of how the brain changes during this critical period of development.
通过对这些男孩的两次扫描，科学家可以细致地描绘出在这个重要的发育时期，大脑是如何变化的。

In the field blanking period of transmission line field synchronizing signal, so that the charge, the synchronous scanning, to accurately reproduce the original image.
