Our ENAD(Endoscope AI Detector) Finder is AI-based Software, as a Medical Device, for Computer-aided polyp detection systems in the field of colonoscopy to prevent colorectal cancer. With a prospective study, ENAD has learned from a dataset comprising 220,000 images from 15,000 polyps. To the best of our knowledge, the dataset is one of the largest in the world. Upon the advantage of the dataset, ENAD can detect hard-to-detect polyps, even for a doctor, with a low false-positive rate. Connecting to an arbitrary endoscope in the market, ENAD works in real-time with high compatibility.
