New lung scanning technology could help clinicians overcome the hurdles that come with traditional lung imaging involving apneas and increased exposure to ionizing radiation.

The XV scanner, a product of 4DMedical, will be presented this year at the annual meeting of the Radiological Society of North America in Chicago. It is said to be the world’s first dedicated lung scanner. The California-based company said its new device “represents a significant advance in lung diagnostics.”

“In the history of scanning technology, very few fundamentally new approaches have been introduced since the 1970s and only seven scanning modalities have been introduced in the past 127 years,” said Andreas Fouras, PhD, Founder and CEO of 4DMedical, in a statement. “We believe XV Scanner is the ‘eighth modality.’ respiratory.”

In conjunction with 4DMedical’s XV Technology software, the scanner, which is currently preclinical, is able to accurately assess areas of high and low ventilation in all parts of the lung and during all phases of breathing. It can be performed in less than five seconds and is performed without the expense of additional radiation exposure that comes with standard CT scans, as the scan requires less radiation than a traditional chest X-ray.

Using XV Technology software, the scan is analyzed to numerically quantify and display regional lung deficiencies in great detail. This comes in the form of a detailed ventilation report that includes a color-coded four-dimensional animation of the patient’s respiratory lung. The Ventilation Report offers clinicians “very detailed maps of lung function” that they can use as a guide to manage treatment.
