Paper Abstract

Digital subtraction angiography images were obtained of a phantom containing 1 mm diameter vessels. The iodine concentrations ranged from 5 to 50 mg/cc, which permitted the detection threshold iodine concentration to be determined. The source to image receptor distance was 105 cm, and image magnification was varied between 1.15 and 2.0. One experiment was performed at an input exposure of 1 (mu) Gy per frame, and a second experiment was performed at 4 (mu) Gy per frame.
