Vibration Response Imaging

Vibration response imaging or VRI, is nominally a medical VR visualisation technology, although it has obvious uses in other fields. It was developed to image patient lungs, and works via detecting vibrations within the target body, via sensors deployed to either side, pressed against the surface.

With lungs, when each sac expands, it creates a tiny displacement shockwave which can be picked up via extremely sensitive haptic detection when the wave reaches the sensor.

Below, we offer a selection of links from our resource databases which may match this term.

Ultrasensitive Imaging: Hunting Every Photon
As the demands for precise imaging in fields such as medicine, astronomy, and real-time machine vision in hostile environments continue to increase, so the demands placed on imaging equipment become ever more stringent. An imaging method based on Single Photon Avalanche Photodiodes (SPAD) offers the potential to ease this bottleneck greatly.

The Brain Unveiled
Technology Review's long, and in depth look at the rise of diffusion spectrum imaging, and how this new neural interface imaging technique is rapidly accelerating the study of both human and animal brains to an extent unparalleled by any previous imaging technique, even fMRI.

Brain Reading: Diffusion Spectrum Imaging
Diffusion spectrum imaging is a new technique at time of writing, which allows magnetic resonance brain imaging, at a much higher level of fidelity than fMRI permits.

Using VR and Phased Imaging to Track Alzheimers Disease Progression in New Ways
In mid 2012, Swiss researchers turned the world of alzheimers plaque imaging on its head: by combining a phased imaging source and an integral VR model generator, for the first time ever we can now track the formation of Alzheimers plaques in real-time in living patients.

Resource List: Medical Imaging

AR based Medical imaging technologies really began to take off in the early 2000s. There are a growing range of holographic, projective, interactive gesture recognition tools available, which can really make training and diagnosis so much easier.

VR Interfaces: VRIxp
VRIxp is a medical diagnosis device using what is perhaps a novel form of 3D visualisation. It uses audio analysis of vibration deep inside the body to assemble precise structural detail.

Brain Reading: fMRI
fMRI or functional magnetic resonance imaging, is one of the newest brain imaging technologies for the first decade of the 21st century. It is a basic form of Brain-Computer Interaction.
