Paper Abstract

The resolution characteristics of a digital subtraction angiographic (DSA) system have been evaluated under two different magnification techniques, namely; the geometrical magnification, and the electro-optical magnification. 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 re-establish the DSA examination procedure.
