Abstract

Elastography is a non-invasive technique for quantitatively measuring tissue viscoelasticity. To calibrate the elastography system or to evaluate bias and variance between several different elastography systems, a standardized viscoelastic phantom is needed. We have developed a viscoelastic dual-use phantom for ultrasound elastography (USE) and magnetic resonance elastography (MRE) that satisfies the QIBA acoustics specification.
