使用CT的激发扫描功能控制曝光时间能得到更准确的肝动脉期时间。
Using ct arouse scanning function control exposure time can get more accurate liver artery issue time.
在质量控制过程中,噪声是重要的指标之一,由噪声与曝光剂量的函数关系,准确测量噪声还可以作为测量曝光剂量的方法。
The noise is one key parameter on routine quality control. Because the image noise is a function of the dose, precisely measuring the noise is also a method for measuring the dose of ct scanners.
