Lung Scan Technology Reveals Hidden Secrets of Airway Disease

LOS ANGELES, July 15, 2025 /PRNewswire/ -- Researchers at Vanderbilt University, Johns Hopkins University, University of Miami, and The Alfred Hospital studied the lungs of subjects including Veterans using technology developed by 4DMedical called X-ray Velocimetry Lung Ventilation Analysis Software (XV LVAS®).

“We’re now able to see the invisible,” says Dr. Bradley Richmond, a pulmonologist who along with Dr. Michael Lester co-led the study. “XV LVAS technology gives us a window into parts of the lung we’ve never been able to assess so precisely before. It could transform care for patients whose symptoms were previously a mystery.”

For decades, doctors have depended on breathing tests such as spirometry and CT scans to assess lung health. However, some conditions—particularly those impacting the smallest airways—often go undetected, leaving patients without clear diagnoses or effective treatment. Now, with 4DMedical’s XV LVAS technology, clinicians can securely upload fluoroscopy scans for advanced analysis. This innovative system produces detailed, real-time color maps that show how air flows through different lung regions as patients breathe. The results are delivered in clear, easy-to-read reports that integrate into existing clinical workflows.
