Tissue mimicking elastography phantoms
First Claim
1. An abnormal tissue mimicking material for testing elastography imagers comprising an open-cell reticulated mesh material and a gel-forming material suffused into the mesh material, wherein the Young'"'"'s modulus of the abnormal tissue mimicking material mimics the Young'"'"'s modulus of abnormal soft tissue.

Abstract
Tissue mimicking materials for elastography phantoms have elastic, ultrasound, and magnetic resonance characteristics that are characteristic of human soft tissues and well suited for the calibration and performance assessment of elastography imaging systems. In one embodiment, the material is formed from a base material containing an oil dispersed within a gel matrix and at least one inclusion formed from a gel. In another embodiment, the material is formed from a gel-forming material suffused throughout an open-cell reticulated mesh matrix.

20. A method for testing an elastography imager comprising, mapping local elastic strains of a tissue mimicking material to obtain a elastogram of the tissue mimicking material, the tissue mimicking material comprising:
-
(i) a base material comprising a gel-forming material; and
(ii) at least one inclusion of a defined shape at least partially surrounded by the base material, the at least one inclusion comprising an open-cell reticulated mesh material and a gel-forming material suffused into the mesh material, wherein the elastic contrast between the base material and the at least one inclusion is such that the elastic contrast between normal soft tissue and abnormal soft tissue is mimicked. - View Dependent Claims (21)
