| Abstract: | The paper introduces a system of the digital subtraction angiography (DSA), which can complete the subtraction of live image with mask image in time.The system has the function of image sampling and live display and the function of image magnifying and image shifiting by hardware. The largest frame store capeciting can reach 128Mbit, and can basically meet the needs of DSA work in clinics. |
