Abstract

For ultrasound elastography there currently exists no large animal model of liver lesions for testing. In this study, we modeled liver lesions using agarose gel, characterizing the phantoms' elastic and echogenic properties. An equation was derived to express a phantom's Young's modulus as a function of its agarose concentration. Moreover, we altered phantoms' echogenicities by adding various amounts of graphite, and found that its inclusion up to 2% does not significantly affect elasticity. These findings can help to systematically create desired liver tumor phantoms for numerous studies.
