X-ray detector and X-ray photographing apparatus including the same

An X-ray imaging apparatus comprising:

• an X-ray source configured to generate X-rays;
• and
• an X-ray detector configured to detect X-rays transmitted by the X-ray source through an object, the X-ray detector comprising:
• a detector element including a cathode electrode and an anode electrode which are spaced apart from each other and a photoconductive layer located between the cathode electrode and the anode electrode, and configured to absorb X-rays and generate electric charges;
• a first temperature controller configured to contact a first surface of the detector element and is configured to control a temperature of the cathode electrode;
• and
• a second temperature controller configured to contact a second surface of the detector element opposite to the first surface of the detector element and configured to control a temperature of the anode electrode.
