Abstract EN
Medical CT imaging often encounters metallic implants or some metal interventional therapy apparatus.
These metallic objects can produce metal artifacts in reconstruction images, which severely degrade image quality.
In this paper, we analyze the difference between polychromatic projection data and Radon transform data and develop an analytical method to reduce metal artifacts.
Approximate features of metal artifacts can be obtained by a simplified energy spectrum function of x-ray beam.
The developed method can reduce most artifacts, and preserve more original details.
It does not require prior knowledge of x-ray energy spectrum and original projection data, avoiding iterative calculation and saving reconstruction time.
Simulation experimental results show that the method can greatly remove metal artifacts.
