The high numbers of hospitalizations and the level of critical care that many COVID-19 patients require can push healthcare institutions and staff to their limits. COVID pneumonia (viral infection in the lungs), which is detected by a chest x-ray or CT scan, can predict the need for more advanced inpatient care.
A busy hospital may perform many lung CTs per day, potentially affecting the service levels that radiology teams are able to deliver. By prescreening the CT scans of COVID-19 patients, an accurate AI model can quickly pinpoint critical results and enable care teams to zero in on patients who are at high risk for severe complications.
Model tuning, testing, and ongoing training are necessary to create and sustain an optimized artificial intelligence model. Careful attention to traceability, reproducibility, and patient privacy are essential. NetApp and SFL Scientific have developed technology for high-performing COVID-19 lung segmentation that uses a state-of-the-art model and transfer learning. The following image compares human annotations and model prediction of lung lesions in a COVID-19 patient. Our methodology delivers an accurate, trained model in a short time and supports ongoing training and optimization with complete traceability.
Running on a fast and efficient NetApp® storage infrastructure, the model takes an average of just 6 seconds to identify the COVID lesions on each patient scan, which is composed of hundreds of images. This speed is on par with other advanced models and is much faster than a typical human analysis of a chest CT.
