Using micro computedtomography in studies on mice, Bateman found that space radiation rapidly attacks bone health.
应用X射线微型计算机断层扫描技术进行老鼠实验，他发现空间辐射将对骨质健康造成严重破坏。

With the number of detector rows of spiral ComputedTomography(CT)increasing, the radiation dose to the patients appears varieties.
随着螺旋CT探测器排数的增加，病人所受辐射剂量也出现了新的变化。
