Abstract：
:The equipment used in digital subtraction angiography is a combination of x-ray equipment and high-speed image-processing equipment. In this article, the components of a DSA system are described, including the x-ray generator, x-ray tube, image intensifier, television system, analog-to-digital (A-D) convertor, image processor, and image acquisition console, as well as available commercial equipment. Techniques for DSA examination are also discussed.
