Purpose:
The purpose of this study is to create teaching materials that visualize the direction of scattered radiation as directional vectors in a virtual reality (VR) space.
Methods:
The directional vector distribution of scattered radiation during X-ray fluoroscopy was created using the Particle and Heavy Ion Transport code System (PHITS), a Monte Carlo code. The directional vector distribution of scattered radiation was visualized as red arrows using the three-dimensional visualization software ParaView (Kitware, Clifton Park, NY, USA), and the directional vector distribution of scattered radiation was confirmed using the VR headset Meta Quest 3 (Meta Platforms, Menlo Park, CA, USA).
Results:
The direction of the scattered radiation was visualized three-dimensionally in the VR space and checked from any direction. The effect of the protective plate was also confirmed by superimposing it on the dose distribution.
Conclusion:
Visualization of directional vector distribution in VR space is useful as an educational tool that allows the direction of the scattered radiation to be grasped in relation to the position of the fluoroscopy system, patient phantom, protection plate, and the user.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
Virtual Work
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...
