Medical Modeling, Simulation, Informatics and Visualization

MMSIV Overview


The Medical Modeling, Simulation, Informatics and Visualization (MMSIV) Division is dedicated to studying technology’s impact on casualty care in militarily relevant contexts using high-fidelity simulation. The Nexus is a forum for research and collaboration, bringing together scientists, engineers, clinicians, advanced developers, and other stakeholders around simulation events of challenging healthcare and to solve problems together.

The Medical Modeling Simulation, Informatics and Visualization (MMSIV) Division’s purpose is to improve patient safety and quality of care by identifying, developing, researching, and advancing simulation-based technologies to increase training effectiveness of military healthcare providers, improving their capability to provide safer, higher quality of care, from the battlefield to the bedside and beyond.

The MMSIV is a forward-thinking team, whether developing innovative proposals for research and development or analyzing existing simulation-based training devices, training systems, delivery processes, and human performance in healthcare. As has been the history of TATRC’s Medical Modeling and Simulation (MM&S) portfolio since its inception in 1999, the MMSIV team continues to seek opportunities.

The MMSIV team is focused on advancing medical excellence through innovative research and development, with the goals of providing training and assessment platforms to optimally prepare individuals, teams and systems to respond to Military Health System needs, and ensure personnel are ready and able to protect, improve, conserve and sustain the health and resilience of Service members for optimal mission performance across global military activities and operations. The MMSIV:

A. Conceives and conducts innovative research in simulation, to address identified gaps in training capability and to improve training effectiveness for the Joint Force,

B. Study human performance in healthcare through the development of high fidelity physical and cognitive performance models, and

C. Evaluates available and in-progress technologies. For example, how well do various simulators perform? How effectively do they support training?

The MMSIV continues to fine tune its strategy, in preparation to expand its science and technology contributions to the MHS.

This year, MMSIV, introduced a new lab space, the NEXUS. This human performance lab features a 41 camera opto-electronic motion capture space. This space also has the ability to gather finer motor movements through electromagnetic motion caption. The motion capture ability is paired with other physiological monitors such as EEG, GSR, pupillometry, eye tracking, EMG, temperature, and heart rate variability. These metrics aim to show the cognitive demands alongside the physical demands that specific tasks require.
