基于碳纳米管静态乳腺CT的阴极性能测控平台设计

Design and Development of a Platform to Control and Measure the Performance of CNT X-ray Source Based Stationary Digital Breast Tomosynthesis

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。

Carbon nanotube（CNT） cathode based X-ray source is a leading field of CT technology in recent years. Compared with traditional thermal emission X-ray source, CNT X-ray source has some advantages such as miniaturization, high temporal resolution and programmable emission. In order to meet the need of evaluating the performance of CNT X-ray source, the authors developed a measurement and control platform. Within which, the associated program was developed used C＋＋ language in Microsoft Visual Studio 2015 development environment. After testing, debugging, and verification, we can conclude that this program satisfy the user＇ s requirement with robustness user-friendly interface, and high-level automation.
