    • Abstract
  • In the system of CT imaging,for the objects with high density metal,CT images reconstructed by the standard filtered-back-projection(FBP) algorithm generate significant streak artifacts. These artifacts seriously influence image quality and bring huge difficulties for judgment. Correction method of metal artifacts has become the hot and difficult issue of CT technique. The paper formulates the cause of metal artifacts,and sums up the correction methods of metal artifacts developed this year,at last,discusses the investigative foreground of correction methods of metal artifacts.
