The principal objective is to determine the ability of the VRI to assess changes in the lungs before and after pulmonary intervention in patients suffering from airway obstruction. [ Time Frame: Baseline and follow-up up to 3 months ]

Vibration Response Imaging (VRI) in Patients That Are Undergoing Pulmonary Interventional Procedure
Vibration Response Imaging (VRI) in Patients That Are Undergoing Pulmonary Interventional Procedure

Vibration response imaging (VRI) technology, provides a radiation-free dynamic image of the lung, by visualizing vibration energy emitted during the respiration cycle (lung sounds). Airflow in the lungs during the respiration cycle creates vibrations that propagate through the lung tissue; these vibrations are affected by the structural properties of the lungs and may vary in space, time and frequency. Moreover, any structural alteration, such as a bronchial obstruction or space occupying infiltration, is reflected in a corresponding modification of the vibration response.

As obstructions that occur in airways alter airflow, the VRI may provide additional lung function information prior to treatment for airway obstruction and during follow-up. Moreover, the VRI may provide the physician immediate evaluation of the improvement of air flow distribution, quantitative and qualitative measurements. Furthermore, the VRI is a non-invasive, radiation free procedure which is simple and doesn't require the level of patient effort required for lung function test and other evaluation.
