X vs Rad Index

X-ray Scattering Simulator is a mobile application tool for demonstrating radiation scattering virtually. The demonstrated data is based on real life measurements in a hospital environment. The application is based on Augmented Reality technology (AR) that allows the user to add virtual 3D elements to the real-world environment through the camera of the mobile device. The objects in this application are the patient, X-ray machine and a color map depicting the radiation scattering. The purpose of this application is to demonstrate how the radiation generated during the X-ray imaging scatters to the environment.
