Several dual‐energy computed tomography (DECT) techniques require a deformable image registration to correct for motion between the acquisition of low and high energy data. However, current DECT software does not provide tools to assess registration accuracy or allow the user to export deformed images, presenting a unique challenge for image registration quality assurance (QA). This work presents a methodology to evaluate the accuracy of DECT deformable registration and to quantify the impact of registration errors on end‐product images.

评估用于双能CT处理的商用可变形图像配准算法。

几种双能计算机断层扫描（DECT）技术要求可变形的图像配准，以校正低能量和高能量数据采集之间的运动。但是，当前的DECT软件不提供评估配准精度的工具，也不允许用户导出变形的图像，这对图像配准质量保证（QA）提出了独特的挑战。这项工作提出了一种方法，用于评估DECT可变形配准的准确性，并量化配准误差对最终产品图像的影响。
