摘要
传统的X射线成像对软组织的分辨率较差 ,而硬X射线相位衬度成像不仅可以对软组织良好成像 ,而且可以活体观察细胞内部结构 ,现已进入临床应用阶段。本文综述了硬X射线相位衬度成像的概念、成像原理、成像特点和临床应用情况。
The resolution of traditional X-ray imaging to soft tissues is bad, but at the help of hard X-ray phase-contrast imaging, not only fine development on soft tissues can be gotten, but vital observation to internal structure of cell can also be done, it is carried on in clinical application. This review describes the concept and principle of the hard X-ray phase-contrast imaging, and its imaging features and the condition of clinical use.
