Dose reduction low pulse-rate fluoroscopy may be accomplished by integrating a magnetic video disk recorder into an x-ray system. Playback of the stored television image between x-ray pulses results in a flicker-free continuous image with actual dose reduction ranging from 2 to 60 times, depending on the pulse rate used. This system was applied successfully to cardiac catheterization and selective coronary arteriography, resulting in an estimated average dose reduction of over 2 times.
