Design and characterization of a tissue-mimicking phantom for ultrasonic elastography

摘要：

Tissue-mimicking phantoms are essential for theinvestigation of ultrasonic elastography. A modifiedpolyacrylamide gel based tissue-mimicking phantom is developedin this paper. It shows greater stability than phantom based onphysical gel, such as gelatin and agar. The elastic andechographic properties of this phantom are determined by theconcentration of acrylamide and graphite powder respectively.Both indentation testing and transient elastography are used tocharacterize the elastic properties of this phantom. The results arealmost consistent with each other. Our work indicate thatYoungs modulus of the polyacrylamide gel based tissue-mimickingphantom is similar to that of human soft tissue, whichranged from several kilopascal to a few tens of kilopascal.
