Claim 8:
9. A detector element determining method for an X-ray computed tomography apparatus including a main detector for imaging, and a correction X-ray detector including a plurality of detector elements configured to detect X-rays, wherein the plurality of detector elements were originally manufactured for use in the main detector but were rendered not usable for the main detector because a defective detector element is included therein, the method comprising:
detecting a detector element array including a plurality of detector elements including a defective detector element, from a plurality of detector element arrays manufactured to be used in the main detector;
implementing the detected detector element array as the plurality of detector elements of the correction X-ray detector; and
determining detector elements to be used in generating correction data, from the plurality of detector elements included in the implemented detector element array.
