Imaging capability of an experimental digital subtraction angiography unit

WJ MacIntyre, W Pavlicek, JH Gallagher, TF Meaney, E Buonocore and MA Weinstein

We evaluated an experimental digital subtraction unit in terms of field uniformity, linearity of signal response to x-radiation, response of the log amplifier, and imaging capability as measured with the Rose phantom. For comparison, conventional film subtraction phantom measurements were made. Our results indicate that this unit exhibits greater sensitivity to contrast media than conventional film subtraction units.
