PROBLEM TO BE SOLVED: To provide a method requiring less memory demand and less computing time to generate images with different image characteristics from measured data by computerized tomography. SOLUTION: In this method for generating the images with different image characteristics from the measured data by computerized tomography, the first image data B1 (xi , yi ) of the first image with the first image characteristic are computed by convolution of the measured data 11 by a first convolution core constituted for the generation of the first image characteristic, and the following reverse projection 12, but in this computing method, the first image data B1 (xi , yi ) are subjected to filtering 13 to acquire the second image data B2 (xi , yi ) of the second image with the second image characteristic. |
