论文摘要
我们提出了一个新的客观数值功能数字，以帮助评估和比较由双能射线照相系统产生的组织选择性图像。通过确定成功的目标度量的要求并在各种方案中进行分析来开发指标。提出的双能减法效率（DSE）指标充分描述了所有模拟图像场景的多种图像属性，表明其能够准确，客观地描述图像质量。所描述的DSE及其测量方法可以成为一种工具，可以客观地和定量地表征双能射线照相图像质量，从而改善了系统比较，开发和优化。
We propose a new objective numerical figure of merit to aid in the evaluation and comparison of tissue-selective images generated from dual-energy radiography systems. A metric is developed through identification of the requirements of a successful objective metric and analyzed in a variety of scenarios. The proposed Dual-Energy Subtraction Efficiency (DSE) metric adequately describes a multitude of image properties for all simulated image scenarios, indicating its ability to accurately and objectively describe image quality. The DSE and its measurement method described can become a tool to characterize dual-energy radiographic image quality objectively and quantitatively, allowing for improved system comparison, development, and optimization.
