Development of an application to visualise the spread of scattered radiation in radiography using Augmented Reality.

As radiation is widely used in medical institutions, the lack of radiation protection education for health workers increases the risk of radiation exposure. The purpose of this study is to develop an application for radiation medical personnel that visualizes the distribution of scattered radiation by using augmented reality. The accuracy of the Monte Carlo simulation was verified. The system construction for mobile imaging and the behaviour of scattered radiation, when irradiated with X-rays, were simulated. The behaviour of scattered radiation was displayed three-dimensionally in virtual reality using ParaView. Subsequently, an application to visualize scattered rays was developed in Unity for tablet devices. An application with a sense of reality was developed by visualizing the scattered radiation distribution of a mobile imaging in a real space in augmented reality in a three-dimensional size, which is close to the actual size. The radiation dose could be estimated at any position, and the behaviour of scattered radiation became easier to understand.
