Book excerpt: The objectives of this project were to develop computer based models of soft tissues that could eventually be integrated into virtual reality-based surgical simulators. To that end, we have developed a number of computer algorithms that span the scales from the microstructural to the phenomenological, and from 1-D to 3-D. For the 1-D case, we have developed a model of fractional order viscoelasticity. For the 3-D case, we have developed an invariant-based formulation of dispersed isotropy and implemented it in a model of blood vessel. Although the later employs as statistical measure of fiber dispersion, both a essentially phenomenological models. To implement tissue microstructure, we developed a micromechanical model based on the General Method of Cells. Through this model, we were able to model fiber-matrix interactions explicitly. These models are currently being validated and implemented into larger organ simulations.

Book excerpt: Soft tissue properties represent a major and significant unknown in the domain of medical modeling and simulation. This program presents a 4 year research effort in defining tissue characteristics of three distinct organs - liver, spleen, and kidney- in vivo. Over the course of this program, we will use novel methods of tissue interrogation to characterize non-linear behavior during slow deformations, as would commonly be seen during surgical manipulations. We will then develop mathematical models which can be optimized to permit near real-time representations of organ behaviors, including the boundary characteristics of organs in situ. During this first year, we examined the in vivo deformations of porcine liver using two different instruments, and determined close agreement between the methods. We initiated mathematical models of our experimental measurements. We also established an experimental standard to compare different datasets, and to measure accuracy of mathematical models of tissue properties. These data were not previously known.
