X-ray photographs which have acquired the scene with no contrast agent are assumed to indicate the get more info history tissue that is usually not of desire. If we now subtract the originally obtained track record image from an X-ray impression with distinction and believe that no affected person movement has taken position, we can easily measure the attenuation triggered only by the injected contrast agent. Since the contrast agent is limited to the vessel technique, it's been injected to, the end result of this kind of subtraction will be a visualization in the vessels only.
