Realization of a poro-elastic ultrasound replica of pulmonary tissue

Biomatter. 2012 Jan-Mar;2(1):37-42. doi: 10.4161/biom.19835.

Abstract

In this work we describe the fabrication of a biocompatible hydrophilic scaffold composed of cross-linked gelatin that mimics the porous three-dimensional structure of pulmonary tissue as well as its water content and mechanical properties. The lung replica also reproduces the characteristic sonographic signs of pulmonary interstitial syndrome, the B-lines or ultrasound lung comets.

Keywords: B-lines; echographic signals; gelatin; hydrogels; lung replica; mechanical properties; porosity.
