摘要:
针对光栅X射线相位衬度成像技术中如何获取高辐射通量和高空间相干的台式X射线源的问题,研制一种桌面X射线源.与传统X射线源不同,其阳极采用平行深沟道阵列的结构靶,灯丝发出的电子经加速聚焦后作用于结构靶,产生高辐射通量的一维相干X射线,其焦斑呈平行线阵列结构分布.将这种X射线管用于基于光栅的X射线相衬成像系统的光源,利用5步相移法得到了新鲜鸡翅的X射线相衬图像照片.
Abstract:
A challenge of grating-based X-ray phase-contrast imaging technology on practical applications is how to obtain a table-top X-ray source of high radiation flux and of high spatial coherence.Such an X-ray source is presented in this paper.The conventional anode of X-ray tube is superseded by a structured target that is formed by a group of parallel deep line grooves.When electrons from filament are accelerated to impinge the target,X-rays of high flux with one-dimensional coherence are emitted with a focal spot of parallel lines.When the tube was used as the X-ray source of grating-based imaging system,a phase image of a fresh chicken wing was obtained by 5-step phase-shifting method.
