The comparison of scatter removal on prostate (B) dataset between our method and the recent work of Niu et al., 2012. From top to bottom is the sagittal, axial and coronal view respectively. Display contrast: [−400 500] HU. Niu’s method gives a high-contrast image, but it contains streaking artifacts and the sacrum in the coronal view is corrupted and incomplete due to the truncation errors in the forward projection.
