摘要
尽管X射线在100多年前就被发现，但X射线的产生技术的发展却相当缓慢．最近发明的碳纳米管X射线源有望彻底改变生物医学X射线成像．碳纳米管X射线源已经成功地应用在几种生物医学成像技术，包括小动物的动态微米CT和乳腺癌的静态乳房断层合成成像．将来，碳纳米管X射线源将在生物医学成像中实现更多应用，其中一个显著的可能是基于静态碳纳米管X射线源的多源CT．
Although discovered more than 100 years ago, X-ray source technology has evolved rather slowly. The recent invention of the carbon nanotube （CNT） X-ray source technology holds great promise to revolutionize the field of biomedical X-ray imaging. CNT X-ray sources have been successfully adapted to several biomedical imaging applications including dynamic rnicro-CT of small animals and stationary breast tomosynthesis of breast cancers. Yet their more irnportant biomedical imaging applications still lie ahead in the future, with the devel- oprnent of stationary rnulti-source CT as a noteworthy exarnple.
