Paper Abstract

The Quantex DS-20 digital image processor has been evaluated as a low cost alternative for digital vascular radiography. The processor is used in conjunction with a conventional remote radiographic/fluoroscopic system with no generator/processor interface required. (Use of a video-tape system reduces timing problems with minimal image degradation). Phantom studies indicate vessels as small as 1.5 mm can be seen with concentrations of contrast as low as 10 mgΓ/ml. Animal studies show that subtraction images of diagnostic quality can be generated.
