肝脏病灶的插入

2015年Lesion insertion in the projection domain: Methods and initial results
来源：https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4654739/

• projection domain
  
  
• 将分割出的肝脏病灶，重新插回同一病人的不同位置
  All inserted locations had realistic appearance and blended naturally into the liver background.
  
  • Liver lesions were segmented and inserted back into the same patients at a different location
  • (a)–(f) show the original liver lesions
  • (g)–(l) show the inserted liver lesions
• 不同扫描条件下肝脏病灶的结果（全图＋放大图）
  Projection-domain lesion insertion method can reflect the impact of reconstruction parameters on the lesion appearance.
  
  • (a) The patient image reconstructed with a FBP B40f kernel and 2 mm slice thickness
  • (b) The hybrid image reconstructed with a FBP B40f kernel and 2 mm slice thickness
  • (c) The hybrid image reconstructed with a FBP B40f kernel and 5 mm slice thickness
  • (d) The hybrid image reconstructed with a SAFIRE I40f kernel (strength of 5) and 2 mm slice thickness

2016年Validation of a Projection-domain Insertion of Liver Lesions into CT Images
来源：https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5026898/

• inserted lesions that received a score of ≥7 (ie, probably real)
  
• inserted lesions that received a score of ≤3 (ie, probably inserted)
  

手术探针的插入

2022年Framework of metal insertion in the projection domain for image quality optimization in interventional computed tomography
来源：https://pubmed.ncbi.nlm.nih.gov/35721310/

• metal insertion
  
• insertion results（插入不同数量的探针）
  
  • 第一行是一个case。第一张：包含真实的三个探针；第二张：包含真实的四个探针；根据前两张：第三张在第一张上面插入了一个探针。
  • 第二行是一个case。第一张：包含真实的一个探针；第二张：包含真实的四个探针；根据前两张：第三张在第一张上面插入了三个探针。
• insertion results（在不同域插入探针）
  
  • 从左到右：图像域插入探针（没有伪影），投影域插入探针，两者的为彩图

  The mean SSIM of the small region-of-interest (~12mm width) centered at the inserted nodules was approximately 0.94.
  
  • CNN：the proposed lesion-insertion convolutional neural network (CNN)
  • Reference：standard projection-domain insertion
