摘要：

A ray tracing algorithm for modeling millimeter waves in a whole body imaging system is presented. Ray tracing is a well-known method for approximating high-frequency wave behavior and is well suited for implementation on graphics processing units (GPUs), presenting computational speed advantages over conventional full-wave modeling techniques. This method leverages the NVIDIA OptiX engine to ensure computational efficiency. Numerical results in this work are compared with conventional two-dimensional method of moments solutions to assess accuracy and computational times are compared with a three-dimensional GPU implementation of the modified equivalent current approximation.
