Development of scattered radiation distribution visualization system using WebAR

Radiation protection education is difficult for some radiological workers to taking because they are busy with medical work. In radiation protection, understanding the behaviour of scattered radiation is important for reducing exposure. Although applications that visualize the behaviour of scattered radiation using augmented reality or virtual reality have been developed, such applications are limited by the need to download the application and the performance of the device. We have developed a system that can be used in a web browser to visualize the behaviour of scattered radiation more easily. Monte Carlo method was used to simulate the behaviour of scattered radiation during radiography using a portable X-ray machine. An augmented reality (AR) system was developed using A-Frame, an open-source web framework, and AR.js, which adds the AR function. Finally, the behaviour of scattered radiation was observed using various devices. With AR, the behaviour of scattered radiation was visualized in three dimensions. The newly developed AR system can be used with web browsers to easily learn the behaviour of scattered rays without the need for special devices.
