We report the evaluation of a prototype dual-energy implementation using rapid kVp switching on a clinical computed tomographic scanner. The method employs prereconstruction basis material decomposition of the dual-energy projection data. Each dual-energy scan can be processed into conventional single-kVp images, basis material density images, and monoenergetic images. Phantom studies were carried out to qualitatively and quantitatively evaluate and validate the approach.
我们报告了在临床计算机断层扫描仪上使用快速千伏切换对双能成像原型进行的评估。该方法采用双能投影数据的重建前基础物质分解。每次双能扫描都可以处理成传统的单千伏图像、基础物质密度图像和单能图像。进行了体模研究以定性和定量评估及验证该方法。
