基于碳纳米管阴极的X 射线源与成像技术进展

ssesses several desirable attributes such as Рminiaturization, fast response time, efficient-focusing and improved control of emitted electrons. Thus, an imagingР372 CT 理论与应用研究 22 卷Рtool based on these attributes will contribute significantly to the field of X-ray imaging within both medicine and Рindustry. In this paper, the development T cathode based X-ray source and imaging methodologies will be Рdiscussed.
