X射线工业CT关键技术的研究

Aim to align with the needs of the in-depth research and production of Industrial CT equipment. Focus on the study of the most critical technical problems in the production process of CT equipment. Methods involved: local scanning of ROI; a local reconstruction algorithm; an x-ray hardening and calibration system of image; a fast reconstruction algorithm; such image reconstruction technologies as reconstructing high resolution image.via low-resolution data, among others. Results: there has been some breakthroughs and remarkable progress with the success in developing the customized image-related software of tomography that has been applied to three industrial CT systems. The study will play an important role in promoting the application and development of industrial XCT technology in China.

在已有研究开发的工业CT系统基础上，结合典型应用需要，解决提高局部分辨率的描扫技术，X身线实际谱的硬化校正方法，感兴趣区的二维和三维CT图象技术等关键技术。使系统的算法研究结合实际需要向应用转化，实现研究成果向应用推广的转化过渡。推动工业CT技术在我国的实际应用和发挥作用。
