An X-ray detection system includes an X-ray generation device and an X-ray detector. The X-ray generation device includes an X-ray emission unit and a first sensor unit. The X-ray detector includes an X-ray reception unit for receiving X-rays from the X-ray emission unit, a data detection unit for detecting data from the X-ray reception unit, a second sensor unit, a computation unit for computing correction data using a distance between the first sensor unit and the second sensor unit, and a data correction unit for receiving a data signal from the data detection unit, receiving the correction data from the computation unit, and then generating corrected data.
