VR and telepresence may have much to offer with its human computer-interfaces, 3D visualization and modeling tools. For example, radiation planning can be aided by adjusting virtual laser beams on a virtual body and seeing how well they will converge on a tumor. In other applications, see-through view glasses can be used to superimpose live ultrasound images of a fetus onto a pregnant woman's abdomen. See-through displays could also be used to view realtime information such as patients' vital signs during surgery. Motion analysis The advanced input sensors of VR can be used for motion analysis, rehabilitation and physical therapy.
Motion analysis can help train athletes to prevent injuries and improve performance.
In rehabilitation and physical therapy, full body suits may pinpoint motor control problems. In other applications, virtual environments could be adjusted to the level of the user. For example, it may be easier to learn how to juggle if you started in an environment with reduced gravity. Modeling Advanced 3D modeling tools can be used to develop useful models of the human body and design artificial organs. Medical professionals can use VR to study the body by navigating in and around it.
