X-ray image tube, x-ray image tube device, and x-ray equipment

The present invention aims to provide an X-ray image tube where the image of the appropriate concentration to increase the contrast can be obtained without increasing the X-ray irradiation dose. Absorbed or scattered X-ray in the object emits light input surface formed on the inside of the input window (14), is further convert the light into electrons by the photoelectric surface for converting the electrons, the focusing electrode (19) in is converged while being accelerated and directed to the anode (20) side. The anode (20) guided on the side electrons are visualized by fluorescent (18), luminance and color depending on the distribution of the incident X-ray, a glass plate (17) colors corresponding to the dose of X-rays displaying an image.
