Abstract
The resolution characteristics of a digital subtraction angiography (DSA) system have been evaluated under two different magnification techniques, namely, the geometrical magnification technique and the electro-optical magnification technique. It has been found that the DSA system resolution is less dependent on the focal spot size [or modulation transfer function (MTF)] than that of routine radiographic angiographic studies. The evaluation results have been utilized to reestablish the DSA examination procedure.
