    • Abstract
  • Aiming to the scatter artifacts for the flat-panel detector-based cone beam CT,a scatter correction method which need adding a Beam Attenuation Grid between the X-Ray source and the tested object was proposed.This study firstly described the device of the Beam Attenuation Grid,then educed the scatter correction algorithm based on the Beam Attenuation Grid.In order to improve the feasibility of this method,the cylinder phantom was experimented.The result showed that the method can effectively reduce the scatter artifacts and increase the quality of the reconstructed slice image.
