We are talking about new imaging technology for the human body! Israel-based Deep Breeze Ltd. has announced receiving the CE mark, “declaring the system ‘safe and effective’ and allowing the company to market the technology to physicians in European Union countries.” The company describes its one-of-a-kind system that visualizes lungs through a tiny body vibrations, caused by an air flow in lungs:
The VRIxp is a radiation free medical device that is expected to allow physicians to easily obtain a series of dynamic images, designed to show the shape and condition of the lungs in real time. The VRIxp has potential to provide visual representations of not only structural changes in the lungs, but also functional changes.
VRIxp only receives and processes energy and does not emit waves or radiation to the body. The VRIxp visualizes vibration energy emitted throughout the respiration process. The energy is accumulated during the breathing cycle by a proprietary accumulation method. VRIxp algorithm slices this energy within a regular interval, inside a predefined frequency band. The output is a series of frames that when played in sequence visualize in real time the dynamic movement of air in the lung…
The vibrations are collected by a spatially distributed array of pressure sensors. The algorithm combines the output signals from a bank of band pass filters, sliced over regular time intervals, to produce a sequence of images which reflect the vibration properties at each pixel position and at each interval.
In the case of the VRIXP, the device’s sensors record vibration energy created by the air flow traveling down (during inspiration) and up (during expiration) the bronchial tree. The vibrations propagate through the lung tissue and structure; the characteristics of the vibrations are modified accordingly. The vibration energy is then transmitted to the hardware motherboard, which allows proprietary patented software to turn the vibration energy into a dynamic image.
