System and method for correcting for metal artifacts using multi-energy computed tomography
摘要：
A method is provided. The method includes acquiring a first dataset at a first energy spectrum and a second dataset at a second energy spectrum. The method also includes extracting a metal artifact correction signal using the first dataset and the second dataset or using a first reconstructed image and a second reconstructed image generated respectively from the first and the second datasets. The method further includes performing metal artifact correction on the first reconstructed image using the metal artifact correction signal to generate a first corrected image.
摘要（中）：

提供了一种方法。 该方法包括以第二能量谱获取第一能量谱的第一数据集和第二数据集。 该方法还包括使用第一数据集和第二数据集提取金属伪像校正信号，或者使用分别从第一和第二数据集生成的第一重建图像和第二重建图像。 该方法还包括使用金属伪像校正信号在第一重构图像上执行金属伪像校正，以产生第一校正图像。
