4Dx was interviewed by AuntMinnie.com, an influential community site for radiologists and related professionals in the medical imaging industry.
In the article “Advanced visualization tool assesses lung disease”, Eric Barnes interviewed the 4Dx team on the new technique they have developed that combines fluoroscopy and advanced visualization to generate high-resolution images of the motion and airflow of lung tissue.
“The patients breathe under fluoro and we can record the motion of the tissues, and from that we can quantify a number of things, like ventilation,” said Andreas Fouras, CEO and Founder of 4Dx.
4Dx uses software to segment and track the bronchial tree and estimate airflow inside that part of the body. The team explained that, assuming air inside the lung and lung tissue is incompressible, the calculated lung expansion directly represents airflow into and out of the lung regions.
Asked how the technology will be used, Andreas explained that they foresee a number of clinical applications.
“Depending on the nature of the disease, it may be easier to see the disease through an image of the ventilation, or it may be easier to see it on the airways themselves where you can see the airflow going through,” he explained. “It primarily depends on whether the disease is restrictive [affecting the tissues] or obstructive [affecting the airways].”
4Dx has tested the technology in animal studies and has started performing human trials with leading Australian and US hospitals.
Andreas believes the images to be very powerful for diagnosis of common lung disease, and, more importantly, for the monitoring and follow-up of a patient as a disease progresses, or as a patient undergoes treatment.
