我们从那个大铁门离开，乘着电梯从地下十层来到地上，先通过视网膜扫描，然后穿过一个带有滑动玻璃门好像飞船的空气舱一样的玻璃房间。
We leave through the steel doors and head up the ten-story elevator, past the retinal scanner, and through glass Chambers with sliding doors that seem like air locks on a spaceship.
例如，当安全门被打开后，一个信号即被发送到扫描仪主机，在安全门被关闭之前禁止扫描。
For example, when a safety door is open, a signal will be sent to the scanner mainframe to prevent scanning until the door is closed.

方法对5例肝门动态扫描ct增强图像有关靶部位的CT值逐层测量，从而得到相应的“CT值时间曲线”，最终找出有效增强周期。
Methods the 5 cases with enhanced CT images were measured at each slice, then the Hu of aim position was obtained and the Hu time curve was got. At last, the valid enhanced period would be found.
