Experimental investigation reveals backscattering improves modeling of metal artifacts in computed tomography, suggesting refined correction strategies.
The problem of suppressing and modeling metal artifacts in X-ray computed tomography has been recognized since the advent of the computed tomography technique and still lacks a universal solution. We investigate the role of backscattering in a genesis of metal artifacts in computed tomography. It is demonstrated that in the presence of strongly absorbing inclusions leading to complete absorption, accounting for backscattering enables the generation of realistic projection data and metal artifacts in the reconstructed images. The results refine the model of metal artifact formation, which is critically important for the development of artifact correction methods of this type.
