NEMA SCA&I
Cardiovascular Fluoroscopic
Benchmark Phantom

For voluntary compliance with NEMA XR 21


Model 901
FEATURES
• Designed for voluntary compliance
  with NEMA XR 21
• Simulates coronary arteries for infant through
   large adult
• Evaluate spatial resolution, motion unsharpness
  and exposure for the entire imaging system



The CIRS Model 901 NEMA SCA&I phantom was desig-ned to evaluate and standa-rdize catheterization image quality. It is the result of collaborative efforts between the Society for Cardiac Angiography and Interventions and the National Electric Manufacturers Association. The phantom specifically enables voluntary compliance with the recently published performance standard NEMA XR 21.

The Model 901 is manufactured from PMMA with x-ray absorption properties similar to soft tissue at diagnostic energies. It contains a variety of static and dynamic test targets for objective assessment of resolution, motion unsharpness and radiation exposure. The sectional design allows for configuration in a wide range of thicknesses from 5 cm to 30 cm simulating PA thicknesses from infants to large adult patients.

The phantom is ideal for routine assessment of the entire imaging system.
