The Virtual Soldier Project Showcase

Virtual Soldier All-In-One Demonstration

Phase I Demonstration showing Physiology Displays, Hotbox Interface and Display, Time Control, Finite Element Displays, Anatomy Display, Forecast Display, Regional Blood Flow Movie and the MPM Modeling Movie

The Holomer

The holographic medical electronic representation or holomer, incorporates all levels of properties (genetic, molecular, biochemical, cellular, physiologic, organ, tissue and whole body) and provides inter-operable cross-linkages from level to level and system to system. Phase I of the project will focus on the heart. The heart holomer will resemble as close as possible the actions that would be performed on a real person.

The P-tag

The dataset for the Virtual Soldier will be stored on the U.S. Army Personnel Information Carrier, the P-tag. This data will be able to be transferred to a number of platforms and medical records (open architecture) to include the medic hand-held computer, standard laptop, standard desktop computer, DoD hospital-based medical record and Veterans Administration (VA) electronic medical record.

Kalman Filters

Kalman filters will help in predicting the state of injuries in the wounded soldier. The Kalman filter is a set of mathematical equations that provides an efficient computational solution of the least-squares method. The filter is very powerful in several aspects: it supports estimations of past, present, and future states, and it can do so even when the precise nature of the modeled system is unknown.

SCIRun Software
Electro-physiology of the thorax

SCIRun is a multifunctional problem solving environment that can be best described as a computational workbench by which the user can "close the loop." All aspects of the modeling, simulation, and visualization processes are linked, controlled graphically within the context of a single application program. Creating an integrated problem solving environment for scientific computing involves many significant elements: representing mathematical and geometrical models; computational solution of the governing equations and visualization of models and results--all within an efficient, parallel software environment.

Edgewarp Image Manipulation Software

Edgewarp3D is a sophisticated workstation package for manipulation of 2D and 3D biomedical images and related data structures by a combination of landmark location, thin-plate spline, and image unwarping and averaging. Edgewarp3D is available from the pub/edgewarp directory on the FTP server at, (for SGI and Linux systems only). Edgewarp was designed and coded by Bill Green with support from NIH grants GM-37251 and DA-09009 to Fred Bookstein. It is built of C and C++ code and makes extensive use of SGI's OpenGL graphics interface. Communication with the user is by textual and graphical interfaces managed using TCL/TK, a general purpose scripting language.
