金属伪影校正

金属伪影校正(MAR)是指去除金属植入物、牙科填充物和手术器械在 CT 图像中造成的明暗条纹。金属对 X 射线的衰减极强,穿过金属的射线会受到射束硬化、光子饥饿、散射和部分容积效应的影响,受损的投影会扩散成贯穿整个层面的条纹。

它在口腔颌面 CBCT、关节置换和脊柱内固定周围的骨科成像,以及放疗计划中都很重要;在放疗中,条纹会扭曲剂量计算所用的电子密度。

经典方法用插值替换正弦图中的金属轨迹(线性插值、归一化 MAR),或者迭代地建模多色物理过程。深度学习方法在图像域、正弦图域或两者中工作,常采用可解释的模型驱动设计。多色神经表示、扩散先验等无监督方法不再需要成对的无金属数据,而这类数据在临床上很少能获得。
