Abstract

To reduce the artifacts and improve the image quality in sparse-view CT reconstruction. A novel improved GoogLeNet is proposed to reduce artifacts of the sparse-view CT reconstruction. This paper uses the residual learning for GoogLeNet to study the artifacts of sparse-view CT reconstruction, and then subtracts the artifacts obtained by learning from the sparse reconstructed images, finally recovers a clear correction image. The intensity of reconstruction using the proposed method is very close to the full-view projective image. The results indicate that the proposed method is practical and effective for reducing the artifacts and preserving the quality of the reconstructed image.
