ABSTRACT:
A radiation computed tomography apparatus that includes a radiation detector having a plurality of radiation detector elements arranged in a two-dimensional manner for detecting radiation passing through a subject, and a reconstructing device for arithmetically reconstructing tomographic image data for a tomographic image of the subject based on projection data for the subject from each of the plurality of radiation detector elements, the projection data obtained from values detected by the plurality of radiation detector elements, wherein the reconstructing device corrects the projection data for each of the radiation detector elements using a corrective value that is correlated with a path length of the radiation through the subject calculated from the projection data, and generates the tomographic image data based on the corrected projection data.
