    摘要: An X-ray imaging device 1 includes an X-ray detection section 2, a cold electron source 3, and a light-shielding coating layer 9. The X-ray detection section 2 includes an X-ray conversion layer 13 made of an X-ray converter material which generates electric charges upon incidence of an X-ray, a first charge injection blocking layer 14 formed on an incidence surface 13a of the X-ray conversion layer 13, and a second charge injection blocking layer 15 formed on a rear surface 13b of the X-ray conversion layer 13. The cold electron source 3 has a plurality of electron emission sections arranged in a matrix form, each of the electronic emission sections being capable of emitting electrons toward the second charge injection blocking layer 15 of the X-ray detection section 2. The light-shielding coating layer 9 blocks incidence of the visible light into the X-ray detection section 2.

    摘要: X-ray camera of the present invention comprises an X-ray irradiation unit, an X-ray image sensor, a controller having a correction factor setting unit, a correction factor storage unit and a correctional operation unit, and a display unit. The X-ray image sensor in the above configuration comprises a sensor such as CCD, TFT, and the like having a scintillator on a surface thereof, and a substrate having the sensor mounted thereon. The correction factor setting unit obtains a value La/Ln by dividing a predetermined brightness reference value La set beforehand by a brightness value La of an arbitrary pixel "n", and sets the obtained value as a correction factor for each pixel. The correction factor storage unit stores the correction factor set by the correction factor setting unit. The correctional operation unit obtains the correction factor from the correction factor storage unit, and performs a corrective operation.
