XV LVAS

Unprecedented Functional Lung Health Detail from X-Ray Scans

XV LVAS® (X-ray Velocimetry Lung Ventilation Analysis Software) is software that processes conventional X-ray scans to provide rich, functional lung health detail not available via other modalities.

Using fluoroscopic lung images from existing hospital equipment, it quantifies regional lung ventilation in a comprehensive but easy-to-interpret report that includes 4D video visualizations. Areas of high and low ventilation are highlighted and ventilation heterogeneity—a recognized indicator of lung health—is quantified.

XV LVAS is provided via Software as a Service (SaaS). Fluoroscopic images are uploaded to 4DMedical for processing with a reference CT.

  • Regional quantification of lung function, including Lung Volume, Ventilation Heterogeneity (VH) and Ventilation Defect Percentage (VDP)
  • Four-dimensional imaging—3D + time
  • Easy-to-read visualization of regional lung ventilation
  • Actionable insights into lung function to better characterize and quantify respiratory conditions and symptoms
  • Uses existing hospital imaging equipment
  • No contrast agents

Applications

4DMedical XV LVAS

The clinical presentation for unexplained dyspnea can be complex; imaging is central to the diagnostic process. But anatomical findings can overlap, lag, or precede clinical symptoms. XV Lung Ventilation Analysis adds significant diagnostic value to reports and gives referrers a new level of actionable information.

Clinicians may look for decision-making support for managing patients with various lung conditions. Our products may provide clinicians with:

Diagnostic Support – Earlier diagnosis and treatment can be assisted by more sensitive and accurate assessments of regional lung ventilation. For chronic and progressive lung diseases with dyspnea, poor exercise tolerance, chronic cough with or without sputum production, and wheezing to respiratory failure involving the airways and/or pulmonary parenchyma that results in changes in regional airflow or ventilatory obstruction.

Surgical Planning – A more intricate and sensitive analysis of a patient’s lung health will allow the optimization of surgical options.

Patient Treatment and Monitoring – XV LVAS is an ideal solution for assisting clinicians to monitor disease progression and therapeutic effectiveness in patients with lung diseases such as COPD and CF.

Clinical Trial Support – XV LVAS provides more sensitivity, repeatable measures, and novel endpoints for new clinical trials.

"XV LVAS software enables clinicians to extract a level of detail and quality about a patient's lung function at far less risk and cost to the patient. We get better information faster and easier that better informs treatment options. It's a real leap forward from the state of the art."
