Analysis of centerline deviations between the actual vessel in the phantom and the virtual 3D model, as generated from an MRA after performing FI using the 2D-3D technique in a the thorax and b the abdomen. The actual vessel’s borders in the fluoroscopy image (red) and the virtual model (green) were outlined manually. A MatLab tool was used to generate a centerline for each vessel and to compare deviations between both centerlines (blue) on a pixel-wise basis every 10 mm. The analysis was repeated for seven angulations of the c-arm (− 90°, − 60°, − 30°, 0°, 30°, 60°, and 90°) in the thorax and the abdomen, respectively
