Radiopaque markers found their use across fields like dentistry and facial reconstruction prior to the patent of the first direct markers in 1998, which indicated anatomical orientation.
In DSA, a fluroscopic sequence of a hard and fast anatomy is obtained. At the same time contrast agent is injected in frequent intervals to the vessel method. X-ray visuals that have obtained the scene without distinction agent are assumed to show the history tissue that is typically not of desire. If we now subtract the originally acquired qualifications graphic from an X-ray picture with distinction and suppose that no patient motion has taken location, we can evaluate the attenuation triggered only from the injected distinction agent. Since the contrast agent is restricted to the vessel technique, it has been injected to, the result of this type of subtraction will be a visualization with the vessels only.
