Low dose CBCT reconstruction via prior contour based total variation regularization (PCTV): a feasibility study
PURPOSE: Compressed sensing reconstruction using total variation (TV) tends to over-smooth the edge information by uniformly penalizing the image gradient. The goal of this study is to develop a novel prior contour based TV (PCTV) method to enhance the edge information in compressed sensing reconstr...
