Human Tissue Properties Database

 

Background/Problem

In this project, we propose to investigate acquiring physical properties for the human body, which are applied as the parameters for our real-time FEM-based simulations.
One of the most important advantages of our simulation platform is accuracy, which can only achieved by using correctly measured physical properties, such as Young's modulus, for human body soft tissues.

Basic Properties Unique to Soft Tissues

• Inhomogeneous Structure
• Nonlinear Large Deformation
• Anisotropy structure
• Viscoelasticity
• Strain rate insensitive
• Incompressible

Minnesota Soft-Tissue Mechanical Property Data Bank

• Mechanical Properties of human soft-tissue
• Currently focus on the Kidney Project related soft-tissues
• Experiments performed within 24 hours of time of death
• Soft-tissues are preserved in physiological solution an warmed to body temperature for experiment
• Uni-axial test for visco-elastic mechanical properties
• Will extend to bi-axial test in near future
