An object of the present invention is to provide an X-ray image tube which enables acquisition of an image of a proper density by increasing contrast without increasing an irradiation dose of X-rays. The X-rays absorbed or scattered through a subject emit light on an input surface formed in an input window, and the light is further converted into electrons on a photoelectric surface which converts the light into the electrons, accelerated and focused by a focusing electrode, and then guided to an anode side. The electrons guided to the anode side are made visible by a fluorescent substance, and an image of a color is projected on a glass plate with a luminance and a color based on a distribution of the incident X-rays in accordance with the dose of the X-rays.
An X-ray image tube comprising:
An X-ray image tube in which a multicolor illuminant is disposed on an output side having a light emission peak in each wavelength region, the multicolor illuminant being disposed to obtain light of a different color in accordance with an intensity corresponding to an intensity of input X-rays by collision with an electron beam obtained by converting, into electrons, light obtained by X-ray-light conversion in a vacuum container of the X-rays which are input through an input window positioned at one end of the vacuum container,
An X-ray image apparatus comprising:
