Vibration Response Imaging (VRI) in Patients That Are Undergoing Pulmonary Interventional Procedure
NCT00672893 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00672893
The ClinicalTrials.gov registry entry for NCT00672893 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 200 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Deep Breeze, which has 2 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Central Airway Stenosis appearing as the primary indexed condition, and to 1 intervention — of which Vibration Response Imaging is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00672893 reports 5 study locations spanning 4 distinct geographic areas — top geographies include Other, Colorado, North Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
