The purpose of this study is to visualize a mathematical human phantom with internal organs and absorbed dose distribution in the phantom as three-dimensional computer graphics (CG).
Each organs of modified GSF* mathematical phantom were displayed as a set of three-dimensional transparent color objects by the ray-tracing method.
Three-dimensional dose distribution data were calculated using Monte Carlo Method. After gray scale modification, the data were displayed with brightness for themselves or superimposed on the phantom image.
By our ray-tracing program, it took about three hours to obtain the image of the phantom head and its organs. It only took a few minutes, however, to re-display the image data on the hard disk. It was suggested that this display system was effective for education and checking algorithms of the Monte Carlo simulation.
