We’ve been following the development of the VRIxp system from Deep Breeze Ltd out of Or-Akiva, Israel for the last three years. Now the company’s flagship product for pulmonary audio analysis has received FDA approval, and the firm has teamed up with GE Healthcare to promote and distribute the device.
Here’s basic info on how the VRIxp functions:
Two sensor array units (V-Array) are placed on a patient’s back to collect the vibration response.
Airflow & turbulence in the large airways induce vibrations of the airway walls.
Proprietary algorithm combines the output signals, filter & process it to produce a sequence of images which reflect the vibration properties at each pixel position and at each interval.
These vibrations are affected by the property of the airways & by the lung tissue.
The VRIxp™ device passively records the vibration energy according to the vibration distribution.
The vibration energy is processed to produce a dynamic image of the lungs.
