Use of the CT scanner as an instrument for foreign body detection and localization was explored under experimental conditions. The results show that a sufficiently dense radiopaque foreign body as small as 0.7mm3 can be detected and localized by presently available scanners.
在实验条件下探索了使用CT扫描仪作为检测和定位异物的工具。结果表明,目前可用的扫描仪能够检测和定位小至0.7立方毫米的密度足够高的不透射线异物。
