Shear Wave Liver Fibrosis Phantom

Model 039
  • Certified shear wave speed measurements
  • Ensure over ten years of reliable use through reinspection and repair services

Best in industry four-year warranty

Shear wave elasticity imaging is an emerging biomarker with many possible applications, most prominently for determining the stage of liver fibrosis in a patient without the need for invasive biopsies. The design of the Shear Wave Liver Fibrosis Phantom, Model 039, was developed and validated in a joint study sponsored by the Quantitative Imaging Biomarker Alliance, and serves as the standard reference tool for determining sources of variance in shear wave elasticity measurements (see references on page 2 of data sheet).

Our Model 039 consists of four phantoms – each filled with Zerdine® gel formulated with differing values of Young’s modulus, a tissue-average speed of sound of 1540 m/s and speckle contrast levels matching that of a healthy liver.

Certification of Young’s modulus will be provided with each phantom for proof of measurements with a precision of +/- 4%. Young’s modulus is tested on batch samples following ASTM standard D575-91 to ensure accurate elasticity. Density will also be measured to allow accurate conversion of shear wave speed to shear wave modulus and Young’s modulus.

Model 039 comes with a carry case for easy transport and phantom set up.

Key Features for Model 039:

The model 039 set contains phantoms with Young’s Modulus Values spanning the range healthy livers to those with cirrhosis, as follows:

  • Phantom 1: 2 kPa
  • Phantom 2: 8 kPa
  • Phantom 3: 18 kPa
  • Phantom 4: 36 kPa

Sets with custom values for Young’s modulus and single units are also available upon special request.
