Sinogram interpolation method for limited-angle tomography

Abstract

This work aims to study and implement a reconstruction method of X-ray tomography able to reconstruct the image from insufficent number of projections. We proposed a new algorithm using the sinogram interpolation. The sinogram restoration is based on the incomplete sinogram available and generates additional data. The reconstructed images were obtained from the interpolated projections, using the classical FBP method, the quality of the reconstructed image depend on the quality and quantity of the projections. Our study showed image restoration performance in case of missing data and shows improved quality of CT images with reduced artifacts in the reconstruction results.
