The Effects of Type and Loading of Radiopaque Fillers on the Properties of Polyether Block Amide Compounds

摘要

Radiopaque fillers are typically dense metal or ceramic powders that affect the energy attenuation of photons in an x-ray beam as it passes through matter, reducing the intensity of the photons by absorbing or deflecting them. The radiopaque compound will attenuate x-ray radiation energy differently than soft tissues and bones. This will then provide the visual contrast yielding an image of the device in the body. A clear picture facilitates accurate placement of the medical device inside the body. The manipulation of the device is monitored using fluoroscopy or x-ray imaging.
