ViP 3.0

 ViP 3.0 / ViP 4.0

 Computable Human Phantoms

At the core of Sim4Life is a comprehensive set of computable human phantoms empowered by the most powerful physics solvers and the most advanced tissue models that provide a realistic biological and anatomical environment for conducting fundamental mechanistic studies, testing the effectiveness and safety of medical devices and treatments, and supplementing clinical trials. Based on the Virtual Population ViP3.0 models of the IT’IS Foundation at ETH Zurich, the computable phantoms are functionalized for prediction of real-world biological and physiological phenomena for any defined patient population. All tissues are linked to a continually updated physical properties database.

All Virtual Population (ViP) models are natively supported with full resolution and do not require simplification.

The powerful Sim4Life meshers allow high-fidelity discretization of the complex computable human phantoms combined with any implant or external device.

A complementary interactive morpher allows the demographic coverage of the parameterized anatomical models to be extended, e.g., to explore underrepresented or pathological anatomies in clinical trials. A flexible physics-based poser is also included with the models.

Physicians and biologists rigorously validate the models and the associated database. Comprehensive documentation for all natively supported computable human phantoms is available.
