SU‐D‐12A‐06: A Comprehensive Parameter Analysis for Low Dose Cone‐Beam CT Reconstruction

Purpose: There is always a parameter in compressive sensing based iterative reconstruction (IR) methods low dose cone‐beam CT (CBCT), which controls the weight of regularization relative to data fidelity. A clear understanding of the relationship between image quality and parameter values is importa...
