Abstract: A method for generating a tomography image and an apparatus for generating a tomography image determine at least one basic pattern of a spatial light modulator for modulating the phase of incident light according to a pixel arrangement pattern; perform spatial shift modulation for moving arrangement of pixels as many as the set number in a vertical or a horizontal direction with respect to the basic pattern; generate tomography images for the respective shift patterns of the basic pattern by using spectrum signals of rays collected from rays which penetrate through the spatial optical modulator and enter a target body; select one pattern for generating the clearest tomography image among the shift patterns of the basic pattern based on the generated tomography images; and generate the final tomography image on the target body by using the selected pattern.
