Backprojection-filtration reconstruction without invoking a spatially varying weighting factor
Purpose: To develop a backprojection-filtration (BPF) algorithm with improved noise properties over the existing BPF algorithm through utilizing (approximate) redundant information in circular cone-beam or fan-beam scans. Methods: The backprojection steps in the existing filtered-backprojection (FBP...
