1. A radiation exposure dose management apparatus that manages a radiation dose received by a subject, the radiation exposure dose management apparatus comprising:
processing circuitry configured to:
obtain image data of the subject;
segment the image data in accordance with organs of the subject;
generate a voxel radiation dose distribution map indicating a radiation exposure dose of each of voxels based on a specific radiation exposure dose model and the image data;
correct the radiation exposure dose of each of the voxels in the generated voxel radiation dose distribution map based on a specific correction factor; and
calculate a radiation exposure dose of each of the organs based on the segmented image data and the corrected radiation exposure dose of each of the voxels in the generated voxel radiation dose distribution map.
