Abstract

Digital Subtraction Angiography(DSA) technique has been widely used to detect vascular diseases and hemodynamic parameters noninvasively. However, there factors in fluencing the resultant DSA image quality. In this paper, several important factors are suggested to improve the DSA image quality based on mathematicical analysis. Experimental DSA images for different filters are shown and also dicussed the difference between original and processed image qualities.
