Niigata University of Health and Welfare

Major in Medical and Rehabilitation Sciences
Field of Radiological Technology


In this field, we conduct research and education on radiological technology, including not only image processing and image analysis, but also the collection of examination and image data, visualization, mining, and evaluation, in order to keep up with advances in state-of-the-art medical equipment and information systems. We also train advanced professionals who can demonstrate leadership and consultation skills in multi-professional collaborations and play an active role in leadership positions.

Master’s Degree

Master of Medical Science in Radiological Technology


The graduate school faculty actively engages in collaborative activities with companies and other universities, aiming to return research results to society. In particular, we actively accept joint research with companies, not only to return research results to society, but also to revitalize and diversify our education. To date, we have conducted joint research with Konica Minolta, Kokuyo, Wacom, NeU, and Toitsu.
