PROBLEM TO BE SOLVED: To provide three-dimensional imaging display equipment independent of x-ray CT equipment that prepares and displays three-dimensional images using projection data collected by x-ray CT equipment without using two-dimensional imaging data reconstructed by x-ray CT equipment. SOLUTION: Convolution data are prepared by convolution treatment of projection data using the projection data recorded in portable recording media by x-ray CT equipment and information obtained at data collection. Imaging three-dimensional voxel is prepared by back projection processing to the three- dimensional voxel domain indicated to the data. The three-dimensional voxel is prepared using this imaging three-dimensional voxel and parameters decided in plural number of interested domains. By performing three-dimensional imaging processing such as volume rendering on the three dimensional voxel, the independent three-dimensional imaging display equipment is provided that prepares and displays three-dimensional images using three-dimensional data directly reconstructed from projection data without using two-dimensional data.
