中文摘要
在这个项目下,我们正在开发一种电子相位步进方法,以取代x射线相衬成像中关键光栅或网格组件的机械扫描。初步结果表明,通过电子控制取代机械运动,获得了几个优势,包括降低成本和系统复杂性,更高的速度,更好的精度和敏捷性。这项技术有助于弥合基于光栅的相衬成像的物理特性与常规x射线成像应用的既定速度和操作环境之间的差距。
英文摘要
Under this project we are developing an electronic phase stepping method which replaces mechanical scanning of the key grating or grid components in x-ray phase contrast imaging. Preliminary results show that by replacing mechanical motion with electronic control, several advantages are gained, including reduced cost and system complexity, higher speeds and better accuracy and agility. This technology helps bridge the gap between the physics of grating-based phase contrast imaging and the established speed and operating environment of routine x-ray imaging applications.
