A dynamic phantom for generation of contrast bolus curves for the evaluation of digital subtraction angiography systems.

Abstract:

:A solid dynamic phantom has been constructed, which allows quantitative measurements of the signal-to-noise ratios in processed images from digital subtraction angiography (DSA) units. Profiles of silicone rubber placed in concentric circles on a plate which is rotated in the image plane generates bolus curves with five different transit times in each examination. The phantom is suited for measurement on DSA units working with matched or recursive filtering.
