A GPU-Accelerated 3D Visual Simulation Platform of X-Ray Digital Imaging Based on Unity

X-ray digital imaging is an advanced and widely used non-destructive testing technology, X-ray digital imaging system faces some problems in actual inspection such as high costs and radiation effects. Computer simulation technology, which comprehensively applies mathematics, computer graphics and image processing technology, can solve these problems well and has its own advantages. At present, most of the research on X-ray digital imaging simulation has slow imaging speed, poor visibility and poor interaction. In this paper, we make a mathematical model for X-ray digital imaging and build a 3D visual simulation platform in Unity. By using GPU acceleration technology, the imaging speed is reduced to only a fraction of a second which can satisfy real-time interaction. This simulation platform has good demonstration and comfortable user experience based on the 3D visualization technology. This work will promote the applications of computer simulation technology in X-ray digital imaging technology.
