Abstract:
1. An X-ray imaging apparatus, comprising: an X-ray irradiating unit configured to irradiate an X-ray to an object; an X-ray detecting unit configured to detect the irradiated X-ray; an image creating unit configured to create X-ray image data based on data detected by the X-ray detecting unit; a moving mechanism configured to move the X-ray detecting unit to the object; a capacitance sensing unit, including an electrode which is positioned so as to cover at least part of a detection plane of the X-ray detecting unit, configured to obtain a capacitance value of the X-ray detecting unit by the electrode; an adjustment unit configured to correct the capacitance value based on a selection of a correction coefficient from a plurality of correction coefficients related to object information; and a distance measurement unit configured to measure a distance between the object and the X-ray detecting unit based on the corrected capacitance value.
