| 中文摘要: |
| 临床越来越多的患者接受金属植入手术。由金属植入物产生的金属伪影对利用CT图像进行术后评估与肿瘤诊断造成极大困难，易导致误漏诊。在滤波反投影重建算法、迭代重建算法基础上改进的校正方法近几十年来不断取得新的进展。本文对去除金属伪影技术的发展现状进行综述。 |
| 英文摘要: |
| More and more patients were treated by surgery with metal implants in clinic. Metal artifacts in CT images caused by metal implants brought challenges for postoperative evaluation and diagnosis of tumor. It also led to the possibility of missed diagnosis and misdiagnosis. In recent decades, the improved methods based on filtered-backprojection and iterative reconstruction algorithms have great progresses in reducing effects of metal artifacts. The actuality of techniques for metal artifact reduction were reviewed in this article. |
