Even the most experienced doctors can't catch every tiny polyp during an endoscopy, a screening of the digestive system. But even in routine exams, the stakes are high -- missing an early warning sign of cancer can lead to delayed diagnosis and treatment, lowering a patient's chances for recovery. To cut down on the rate of missed precancerous lesions, one Japanese endoscopist is turning to AI. His startup, AIM (short for AI Medical Service), is building a GPU-powered AI system that will analyze endoscopy video feeds in real time, spotting lesions and helping doctors identify which are cancerous or at risk of becoming so. AI screening could also help clinicians manage a demanding workload: Japanese endoscopists must check more than 3,000 medical images a day, on average.
