American CIRS 039 ultrasound phantom
Product model:
Brief description:The US CIRS 039 phantom provides a set of reference standards for making quantitative measurements of tissue stiffness and is compatible with major ultrasound shear wave modalities, including Fibroscan's Vibration Controlled Transient Elastography (VCTE TM), Sonic Imagination's Shear Wave Elastography, and Acoustic Radiation Force Impulse (ARFI) elastography. Shear wave elastography is an emerging biomarker with many possible applications, notably being used to determine the stage of liver fibrosis in patients without the need for invasive biopsy.

USACIRS 039 Ultrasound Phantom
Introduction:
USAThe CIRS 039 phantom provides a set of reference standards for making quantitative measurements of tissue stiffness and is compatible with major ultrasound shear wave modalities, including Fibroscan's Vibration Controlled Transient Elastography (VCTE™), Sonic Imagination's Shear Wave Elastography, and Acoustic Radiation Force Impulse (ARFI) elastography. Shear wave elastography is an emerging biomarker with many possible applications, notably being used to determine the stage of liver fibrosis in patients without the need for invasive biopsy.
USAThe CIRS 039 phantom includes four models with different stiffness variations: 3, 12, 27 and 48 kPa. The elasticity of the phantom was selected based on the average tissue elasticity at various stages of liver fibrosis. A stiffness of 3 kPa represents the elasticity of healthy tissue, while 48 kPa represents the elasticity of tissue with grade five liver fibrosis. Phantoms can also be manufactured according to user requirements, with customized stiffness ranging from 1 to 100 kPa.
Each model will provide proof of Young's modulus for measurement accuracy+/- 4%. Young's modulus is tested on batch samples according to ASTM standard D575-91 to ensure precise elasticity. The density is also measured to allow for precise conversion of shear wave velocity into shear wave modulus and Young's modulus.
ModelThe 039 comes with a carrying case for easy transport and phantom setup.
