Elasticity QA Phantom (model 049) – CIRS

Any questions or would you like to order this product? Do not hesitate to contact us

The Elasticity QA Phantom (model 049 & 049A) is a tool you can use for both shear wave and compression elastopraphy. These models are the only phantoms commercially available for sonoelastography quality assurance. The phantoms contain targets of known stiffness relative to the background material and range in stiffness, diameter and depth.

Both phantoms come standard with a four-year warranty and carry case.

The Model 049 is a basic QA phantom as it contains two sizes of spheres positioned at two different depths. At each depth there are two spheres that are softer than the background and two that are harder than the background.

Model 049A has a broader range of target sizes than the 049. This phantom has stepped mass targets instead of spheres. Each stepped mass consists of six diameters so that you can evaluate the ability to visualize targets that are located at the same depth and have the same relative stiffness but vary in diameter.

Both models are housed in the same size container as the original Model 049.

Inside of the Elasticity QA Phantom


  • Four types of lesions with discrete elastic moduli
  • Compatible with both shear wave and compression elastography
  • Customized versions available for magnetic resonance elastography
  • Ensure over ten years of reliable use through reinspection and repair service

The phantoms are suitable for determining dynamic range, checking system performance over time, training and demonstrating, and research and development.
