Measurement Tools for the Immersive Visualization Environment: Steps Toward the Virtual Laboratory

September 1, 2007

Author(s)

John G. Hagedorn, Joy Dunkers, Steven G. Satterfield, Adele Peskin, John T. Kelso, Judith E. Terrill

This paper describes a set of tools for performing measurements of objects in a virtual reality based immersive visualization environment. These tools enable the use of the immersive environment as an instrument for extracting quantitative information from

Perfusion Flow Bioreactor for 3D In Situ Imaging: Investigating Cell/ Biomaterials Interactions

July 1, 2007

Author(s)

J S. Stephens, James A. Cooper, Frederick R. Phelan Jr., Joy P. Dunkers

The capability to image cell/material interactions real time in a three-dimensional (3D) culture environment will aid in the further advancement of tissue engineering. This paper describes a perfusion flow bioreactor designed to hold tissue engineering

Strain Induced Alterations in Protein Modified Surfaces and Cellular Response

April 18, 2007

Author(s)

Lisa Pakstis, Joy P. Dunkers

All cells experience strain under physiological conditions. However, experiments that are performed under macroscopic strain conditions prevent a direct correlation of applied strain to cell behavior. Our focus is to measure the local stress/strain

Quantitative, Interactive Measurement of Tissue Engineering Scaffold Structure in an Immersive Visualization Environment

October 2, 2006

Author(s)

John G. Hagedorn, Joy P. Dunkers, Adele P. Peskin, John T. Kelso, Lori Henderson, Judith E. Terrill

We describe a software system that enables the measurement and analysis of tissue engineering scaffold materials from three dimensional images. Essential to this work is the use of an immersive visualization (virtual reality) system that gives the
