Virtual Human Project - Standard Languages for Anatomical and Physiological Modeling

ORNL conducts basic and applied R&D in support of national & international goals

Outline

Motivations for new approach to human modeling

Apply tools of information technology to modeling human biology over wide scale

Virtual Human: an internal research program at ORNL

ORNL takes lead in early Virtual Human effort

Forum established for Digital Human effort

Conferences held to define the Digital Human

Synergy with other comprehensive, integrated human modeling efforts

Workshops/Conferences identified the need to adopt standards for interoperability

What is XML?

XML descriptions becoming common

physioML: An XML for physiological modeling

physioML flexible enough to describe quite different models and interfaces

Example 1: Cardiovascular circuit model

Example 2: Lung fluid transport model

Example 3: Hg-vapor inhalation model

What is an ontology?

How does it differ from XML?

Ontologies may be expressed using RDF (expression of semantics) & XML (syntax)

Ontologies are used in genome and cellular modeling

Digital Human: create anatomical ontology

Visualization tools needed to create anatomical models

Segmentation of CT images

PPT Slide

Future of web-delivered anatomical models

Visible Human in the CAVE

Realistic rendering of heart

To build Virtual Human will require a problem-solving environment

NetSolve developed to access clusters of HPC machines (Grid)

A prototype computational environment for complex 3D flow modeling

PPT Slide

PICMSS Java user interface

Model equations entered using Equation Formulator

PICMSS used to simulate pulmonary function

Common Component Architecture (CCA)

PPT Slide

Conclusion: adopt standard data schemas for anatomical and physiological modeling

Adopting schemas for data and model description will bridge the scales in human modeling
