Abstract

We have developed a high resolution digital subtraction angiography (DSA) system which has a 1024 x 1024 pixel matrix incorporating a high resolution TV camera. The resolution of a DSA system is usually restricted by a TV camera so far. A diode-operating implegnated-cathode SATICON (DIS) imaging tube was selected and the TV camera was operated in slow scan mode with 1125 scan line numbers to improve the resolution of the TV camera. This system was free from degradation in resolution due to 512 X 512 pixel matrix. Diagnostic accuracy was improved by using the high resolution DSA system.
