以碳纳米管作为阴极材料的场致发射X射线源及成像技术是国际上的研究前沿,也是CT技术的重要发展趋势之一。相比传统热电子发射X射线源而言,碳纳米管X射线源具有结构紧凑、高时间分辨率、可编程式发射等优势。为了满足课题中对碳纳米管阴极场发射电流性能的测试与监控需要,在微软公司的Visual Studio 2015开发环境下采用C++作为本程序的编程语言,设计并实现碳纳米管静态乳腺CT的阴极性能测控平台。经测试验证后,本程序的具有操作简便、自动化程度高、界面交互性好等优势。
Field emission X-ray source and imaging technology using carbon nanotubes as a cathode material are the forefront of international research and one of the important trends in CT technology. Compared with the traditional hot electron-emitting X-ray source, the carbon nanotube X-ray source has the advantages of compact structure, high time resolution, programmable emission and the like. In order to meet the testing and monitoring needs of the field emission current performance of carbon nanotubes in the subject, C ++ was used as the programming language of Microsoft Visual Studio 2015 to design and realize the cathode performance of the static breast CT Measurement and control platform. After testing and verification, the program has the advantages of easy operation, high degree of automation, good interface and other advantages.
