Despite our rapidly increasing understanding of lung disease, our ability for effective treatments is critically limited by the lack of tools to measure lung function in a regional manner. Nearly all lung pathologies are associated at the onset of disease with subtle, significant and regional changes in airflow due to changes in tissue compliance and/or resistance. However, the current gold standard diagnostics can only measure pulmonary capacity as an average over the entire lung. As a result, a diagnosis can often come too late because for a loss of lung function to even be measurable, the disease must be well-advanced. Now, for the first time in medical history, the capacity to simply, safely and effectively view and measure regional lung function is here. We are 4DMedical - the medical technology company responsible for the XV Lung Ventilation Analysis Software - the breakthrough lung imaging technology that quantitatively measures the patterns of regional lung function in 4D.
