本文提出了一种新的校正算法的CT图像中的金属伪影使用的技术称为双步骤自适应阈值(DSAT)。提出的伪影校正算法被应用到选定的伪影体模和临床CT图像。利用双阈值技术检测并提取了由于金属引起的投影数据缺失。基于DSAT的算法允许显著减少伪影,并保留校正后的CT图像中的大部分解剖结构。
This paper presents a correction algorithm for metal artefacts in CT images using a novel technique known as dual-step adaptive thresholding (DSAT). The proposed artefact correction algorithm was applied to selected artefactual phantom and clinical CT images. The missing projection data due to metal is detected and extracted by double-thresholding technique. The DSAT-based algorithm allows significant reduction of the artefact and preserves most of the anatomical structures in the corrected CT images.
