ABSTRACT:
A specific slice of a tire is subjected to a high energy radiation which is provided for obtaining projection data of high radiation absorption coefficient portions (steel portions in the tire). The obtained projection data of this steel portions is arranged in a first sinogram. The projection data in this first sinogram is then reconstructed to provide image data. The signal level of the image data is sliced to obtain position data of the steel portions. Based on the obtained position data, the first sinogram for the steel portions is reproduced. This reproduced first sinogram indicates the location of each steel portion. Besides, the same specific slice of the tire is subjected to a low energy radiation which is provided for obtaining projection data of low radiation absorption coefficient portions (rubber portions). The obtained projection data of the rubber portions is arranged in a second sinogram. The second sinogram contains not only the data of the rubber portions, but contains the data of the steel portions. The steel portion data in the first sinogram is subtracted from the corresponding steel portion data in the second sinogram. Then, the subtracted portions in the second sinogram is filled with given data similar to the rubber portion data. Based on the data in this sinogram, image data of the tire is reconstructed.
