Missing wedge reconstruction, processed with NAD. a A WBP reconstruction of aligned, noiseless projections with a 28 ° missing wedge. b The reconstruction from (a) but processed with NAD. c The result of a manual threshold operation on the processed image. d The histogram for (a) with the threshold levels indicated. a Inset regions are ×2 magnified from the phantom (left) and the plain reconstruction; b the NAD-filtered reconstruction (right). The contrast in the right insets of (a) and (b) has been enhanced for the purpose of improved visibility
