Abstract
The correction apparatus comprises a projection image acquiring section for acquiring a measured projection image, a virtual energy setting section for setting a virtual energy different from the measured energy that is the energy of the X-ray irradiated at the time of acquiring the measured projection image, a dual energy decomposing section for calculating a projection image under an assumed condition at the time of irradiating the X-ray of the virtual energy and performing dual energy decomposition, a consistency index evaluating section for evaluating a temporarily corrected image obtained by the dual energy decomposition with a consistency index to identify an optimum condition among the assumed conditions, and a correction image generating section for generating a projection image under the optimum condition as a corrected image.
