摘要
This study examined the effects of missing Radon transform on single-orbit cone beam SPECT image quality, and employed statistical Kriging in the estimation of missing data on Grangeat algorithm for two simulation phantoms. Evaluation studies found that Kriging estimation improved reconstruction image quality for an object containing sharp edges.
