Science that Protects People from Radiation

We conduct research on radiation protection and monitoring of patients and medical staff, and on XR-based education for radiation protection.

Visualizing the "Invisible" Radiation

Using AR/VR/MR (XR) to visualize scattered radiation and dose distribution, we develop educational tools that make protective behavior intuitive.

Education / XR

Toward Safer Radiological Practice

Through Monte Carlo simulation and measurement, we propose scientifically grounded strategies for reducing medical and occupational exposure.

Shielding Design by Monte Carlo Simulation

We accurately evaluate scattered and leakage radiation in X-ray rooms to propose safe, rational shielding designs.

Scatter Evaluation in Fluoroscopy & Angiography

We evaluate scattered-radiation distribution for each C-arm angle, field, and tube voltage to reduce operator exposure.

AR Visualization of Scatter Sources

We present the direction and intensity of scatter sources with AR and 3D models so staff can intuitively find effective protective positions.

About the Laboratory

Visualizing "invisible" radiation in clinical settings for safer radiological practice

While radiation is indispensable for medical diagnosis and treatment, it also entails the challenge of exposure to patients and healthcare workers. Built on radiation protection science, our laboratory aims to realize safe, high-quality radiological practice through dose evaluation and monitoring, radioactive waste management, and the visualization of radiation combined with XR-based educational materials.
