低剂量 CT 去噪

低剂量 CT 去噪是指抑制为降低辐射剂量而减小管电流或管电压时,CT 图像中出现的噪声和伪影。探测到的光子减少会增大投影中的量子噪声,重建后表现为颗粒状纹理和条纹,可能掩盖低对比度病灶。

它用于肺癌筛查、儿科成像、反复随访扫描和灌注研究等一切需要控制累积剂量的场景。标准的真实数据基准是 2016 年 AAPM 低剂量 CT 大挑战中的 Mayo Clinic 数据(现以 LDCT-and-Projection-data 在 TCIA 发布),LoDoPaB-CT 则是主要的模拟基准。

方法可以在投影域进行(正弦图滤波、考虑噪声模型的恢复),也可以在图像域进行(RED-CNN 等 CNN、带感知损失的 GAN 去噪器、Transformer),或两者结合,或嵌入使用学习先验或字典先验的统计迭代重建中。自监督方法免去了对成对全剂量图像的需求,扩散模型也越来越多地被用作先验。
