Four-dimensional X-ray imaging technology developed by Monash Engineering provides a state-of-the-art, non-invasive way of understanding real time lung motion and airflow. Functional deficits are detected through local differences in movement. Until now, medical professionals have only partially been able to achieve this level of detail, through a complicated jigsaw of static images and other diagnostic tools.

4DMedical (formerly 4Dx) is a spinout company formed to offer software services based on this technology. X-ray images acquired using standard equipment are sent to the 4Dx analysis cloud, where quantitative lung function data is extracted and reported back to the physician. In addition to cancer, this imaging technology will provide unprecedented detail for diagnosis and monitoring of respiratory conditions such as chronic obstructive pulmonary disease, cystic fibrosis and asthma. The end result: improving millions of lives through earlier disease detection and more accurate monitoring of chronic respiratory conditions.

The company received almost $1m in federal funding in April 2018. Read more.

Successful clinical trials were announced in October 2019. Read more.

After a highly successful pre-IPO, 4D Medical is expected to list on the ASX on 14th August 2020. The company's XV Technology™ that provides four-dimensional lung function imaging analysis in real-time has been approved by the FDA, including use in Covid-19.
