Health Sciences(Master’s Course)

Department of Radiation Science

Radiation has been applied in the medical field for over 100 years, and its importance in diagnoses and treatment in the modern medicine is extremely important. Radiation technology has continued to develop through the advancements of hardware and software in equipment engineering, and supports modern medicine. In the Master’s Course of Radiation Science, education and research developed from faculty education on techniques and theories of information engineering, system engineering, and biological science in image diagnosis and radiation treatment are carried out.
