Hiroaki Ikematsu, MD, PhD

The strongest advantage of gastrointestinal endoscopy is early detection and early treatment of gastrointestinal cancer. Therefore, I would like to work with the company and academia to develop new endoscope equipment using the latest technologies such as new imaging endoscope and artificial intelligence (AI).
