WE‐FG‐207B‐09: Experimental Assessment of Noise and Spatial Resolution in Virtual Non‐Contrast Dual‐Energy CT Images Across Multiple Patient Sizes and CT Systems

Purpose: To investigate the noise and spatial resolution properties of virtual non‐contrast (VNC) dual‐energy CT images compared to true non‐contrast (TNC) images across multiple patient sizes and CT systems. Methods: Torso‐shaped water phantoms with lateral widths of 25, 30, 35, 40 and 45 cm and a high resolution bar pattern phantom (Catphan CTP528) were scanned using 2nd and 3rd generation dual‐source CT systems (Scanner A: Somatom Definition...
