Comparison of capsule strain through different liver pressure states

Résumé

Due to its location and anatomy, the liver is a key organ to model for applications in car safety and in computer aided surgical procedures. Its dual blood supply, venous and arterial, involves the vital prognosis of the individual when it is injured. The mechanical behavior of its brittle parenchyma and the Glisson's capsule, which surrounds parenchyma, is a major issue in numerical simulation. Thus, many researches are focusing on the characterization of the Glisson's capsule through tensile tests. Under these test conditions, the initial state of strain corresponds to the sample placed between two jaws and therefore seems far from the initial state of the capsule in - vivo. In order to define the state of strain for tensile test sample of Glisson's capsule, we have measured the strain field of this structure on liver under different pressure levels in portal vein and hepatic artery.
