我们报告了在临床计算机断层扫描仪上使用快速kVp开关的原型双能实现的评估。该方法对双能投影数据进行预构造基料分解。每次双能扫描都可以被处理成常规的单kvp图像、基材密度图像和单能图像。幻影研究进行定性和定量评估和验证的方法。
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.
