Virtual Reality for Medicine

PHYSICALLY-BASED MODELING THROUGH A DYNAMIC ATOMIC UNIT APPROACH FOR HAPTIC RENDERING: TOWARDS NON-LINEAR, VISCOELASTIC, ANISOTROPIC BEHAVIOR: Design of methodology which allows 3D models to be enabled with haptic rendering capability.
T.Kesavadas, A.Chanda

HAPTIC KYMOGRAPH: A TELE-HAPTIC INTERFACE FOR DIAGNOSTICS OF HUMAN PULSE: The Haptic Kymograph is an innovative tele-haptic interface for capturing and transmitting human pulse for medical diagnostics. A user can see, hear and touch the pulse of a patient in a remote place in real-time.
T.Kesavadas, Y. Kim

IMAGE GUIDED SURGERY IN NEURO-ENDOVASCULAR PROCEDURES: Assisting interventionalists in making decisions about accessibility by providing them with information on stent dimension, vessel curvatures and position and orientation of intervention devices.
T.Kesavadas, K.Hoffmann, N.Subramanian, S.Bhat, R.Agrawal

A NON-INVASIVE SYSTEM FOR MEASURING THE BIOMECHANICAL PROPERTIES OF SOFT TISSUE: Virtual Reality based diagnostic system for medical examination of the human abdomen. It is expected that the system could be used in conjunction with telemedicine systems for remote applications.
T.Kesavadas, J.Mayrose, K.Chugh

LIVING ANATOMY PROGRAM: In advancing our capabilities in the realm of virtual reality based simulators, the development of haptic technology has been a rate limiting factor. The living anatomy program seeks to obviate the need for such technology by designing physical objects based on anatomical components.
T.Kesavadas, A.Kamerkar, N.Subramanian

NEUROSURGERY SIMULATOR IN A VIRTUAL ENVIRONMENT: Neurosurgical procedures are one of the most complicated surgical procedures. This project seeks to provide a means for practicing and developing skills demanded by these procedures by developing a virtual reality based neurosurgery simulator.
T.Kesavadas, E.Coszeralla, N.Subramanian, A.Bhandwale

A VIRTUAL ENVIRONMENT FOR ENDOTRACHEAL INTUBATION TRAINING: This project seeks to provide a means for practicing and developing skills required for endotracheal intubation training. Endotracheal intubations are performed for urgent airway control in injured patients.
T.Kesavadas, J.Mayrose, K.Chugh, D.Joshi

Cultural Heritage Reconstruction

UB Virtual Site Museum: The purpose of this project is to document and publish a uniquely comprehensive report on ancient assyrian palace, by bringing together, for the first time, all new, updated and extant materials and research using leading-edge computer graphics technologies, and to create a multimedia interactive educational and scholarly research tool.
T.Kesavadas, S.B.Paley, Y.Kim

Scientific Data/Information Visualization

DISTRIBUTED DATA FUSION (DDF) TESTBED: VISUALIZATION AND SIMULATION SUPPORT: We are a part of a multidisciplinary group working together to design and develop a DDF testbed to develop, evaluate and test algorithms to perform networking, sensor simulation, target tracking and fusion in a battlefield environment.
T.Kesavadas, G.Srimathveeravalli, C.Mehta

NATURAL OR MAN-MADE POST-DISASTER MONITORING: The purpose of this project is to simulate monitoring of disaster and its relief situation for a control center. When disaster occurs, there normally is huge amount of data flowing into the control center and thus data fusion process is needed for efficient relief action.
T.Kesavadas, Y.Kim, M. Mandiak, P. Shah

INFORMATION PROCESSING FOR INTEGRATED OBSERVATION AND SIMULATION BASED RISK MANAGEMENT OF GEOPHYSICAL MASS FLOWS: The risk of potential volcanic eruptions is a problem that public safety authorities throughout the world face several times a year. Computer simulations of volcanic phenomena permit analysis of loss of life and disruption of infrastructure.
A.Patra, T.Kesavadas, A.Chanda, A.Kamerkar

DYNAMIC TRAFFIC ROUTING: Optimal path finding is one of the critical issues in emergency or disaster relief. The purpose of this project is to overcome common GIS software's limitations, such as longer time of optimization algorithm, restrictions of navigation and static data.
T.Kesavadas, Y.Kim

UNCERTAINTY VISUALIZATION AND HAPTICS IN THE SCOPE OF MINEFIELD DETECTION: Uncertainty Visualization for minefield detection using visual, audio and haptic techniques. Different forms of uncertainty and errors are introduced as the data are derived, transformed and interpolated, and finally rendered.
T.Kesavadas, A.Bisantz, A.Kamerkar, P.Bhide, S.Basapur

PEACE BRIDGE PROJECT: The simulation of what type of bridge configuration to use - Cable, Concrete, Arch, Twin, Suspension? The proposed designs were available in the form of blueprints and it is not easy to make a $350-million decision based just on these. - T.Kesavadas, A.
