Development of Visual Educational Materials for Radiation Protection in Computed Tomography

Abstract The purpose of this article is to develop a virtual reality (VR) instructional environment that allows users to visually experience scattered radiation intensity distribution during computed tomography (CT) is presented. Scattered radiation generated during a CT scan of the head was measured with an air dosimeter to create a dose profile. A color map showing the spread and intensity of scattered radiation was created from the dose profile and used to generate VR content. Scattered radiation was visually recognized using the developed VR educational environment. From the results obtained, it is clear that with the developed immersive teaching material, it is possible to visually recognize the characteristics of scattered radiation in head CT examinations. Users can look back on their own radiation protection methods through virtual experiences with the developed immersive teaching materials.
