Watson can diagnose heart disease by looking at medical images

IBM's Watson technology has helped doctors before, but usually by poring through databases before offering its advice. Now, it's ready to look at the patients themselves -- or rather, their body scans. The AI platform can sift through ultrasounds, x-rays and other medical data to both fill out health records and identify patients who might need critical care. The imaging tech will first be used to diagnose patients with aortic stenosis, where the heart's aortic valve narrows and constricts blood flow. Watson will combine heart imagery with medical records to spot patients who might need follow-up treatments.
