Local ROI Reconstruction via Generalized FBP and BPF Algorithms along More Flexible Curves
<p>We study the local region-of-interest (ROI) reconstruction problem, also referred to as the local CT problem. Our scheme includes two steps: (a) the local truncated normal-dose projections are extended to global dataset by combining a few global low-dose projections; (b) the ROI are reconst...
