Research on Hyperspectral CT image reconstruction and material identification method

Abstract

医学影像是研究如何无创地获取人体解剖和生理信息,为诊断和评估提供依据。影像模式可分为两大类:一是提供解剖信息的结构成像;二是提供生理信息的功能成像。对于某些病例,单一的成像方式往往无法做出全面的诊断。而不同的成像方式往往能够信息互补,从而出现了近来迅速发展的多模式医学成像技术。传统的计算机断层扫描(ComputedTomography,CT)属于典型的结构成像,若要进行非结构改变的病灶定位则必须结合成分信息分析。本论文在CT成像的基础上,引入高光谱重建和辨识,融合CT高空间分辨率和高光谱检测强辨识能力二者的优势,实现结构和成分分析的一体化。目前主流的双能、多能CT的能量是通过X射线球管的电压来...Medical imaging is a study on how to obtain anatomical and physiological information of human, which provides a basis for diagnosis and evaluation.
