Quantitative coronary arteriography: the impact of image zoom and reference object size on diameter measurements

The authors studied the effect various catheter sizes and floating image zoom on catheter calibrated vessel diameters. The pixel sizes of vessel phantoms (0.3-4.5 mm o) were obtained by optimum weighted edge detection. The 2.0 mm and the 3.0 mm phantom served as scaling device for catheter calibrati...
