Together with Delft Imaging, we developed CAD4COVID-XRay: an artificial intelligence software that triages COVID-19 suspects on chest X-ray images. CAD4COVID-XRay has been developed with the intention to support triaging in resource-constrained settings and high-prevalence areas. It became available in the week of March 30th and will be free-of-charge.
COVID-19 is a global health crisis that will long be remembered and that has impacted the lives of millions of people around the world. Both low- and high-resource countries have been greatly impacted by this public health crisis. In response to this crisis, we want to support Ministries of Health and healthcare facilities around the world by leveraging our extensive experience in artificial intelligence and tuberculosis screening, with which we have already screened millions of people around the world.
The ingenuity behind CAD4COVID uses the same technical core as our proven software for tuberculosis detection, CAD4TB. CAD4TB is a significant part of the equation because CAD4COVID was built upon the same high-quality standard as CAD4TB, which is validated by over 40 academic publications and has contributed to screening 6 million people worldwide across 40 countries.
CAD4COVID will generate a score between 0 and 100 indicating the extent of COVID-19 related abnormalities, display such lung abnormalities through a heatmap and quantify the percentage of the lung that is affected. The performance of CAD4COVID in detection of COVID-19 on chest X-ray images is comparable with that of human readers, as shown in an evaluation study published in Radiology.
