Abstract: PURPOSE:To prevent electrification, caused from collision with electrons released from linear negative electrodes so as to keep the electric field surrounding the line negative electrodes to be uniform, by forming electroconductive films on surfaces of both a rear electrode, made of glass serving as dielectric, and spacers. CONSTITUTION:The electron gun of this image display unit is composed of a flat- shaped rear electrode 12 with electroconductive films 12a formed on one side, glass spacers 13, in which both edges of the surfaces making contact with vertical focusing electrodes 3 are ground 13b to be insulated from the vertical focusing electrodes and the opposite surfaces are formed of electroconductive films 13a all over so as to continue with the rear electrodes, and vertical focusing electrodes, so that linear negative electrodes 2 are surrounded by them. Linear negative electrodes 2 are surrounded by flat-shaped rear electrodes 12 and glass spacers 13, which can have the same potential as the rear electrodes 12 and keep the electric field uniform. Since the vertical focusing electrodes 3 have continuity to the transparent electroconductive films 13a of glass spacers 13, the same potential as the vertical focusing electrodes 3 can be realized even in case of heat deformation of the vertical focusing electrodes 3, caused by radiation heat from the linear negative electrodes 2, and then the electric field can be kept uniform.

Abstract: PURPOSE:To obtain a reconfigured image with less picture quality deterioration by reducing a part where an X-ray source and a rotary substrate are crossing by moving the substrate and then generating the reconfigured screen by compensating an obtained data so that an enlargement rate is aligned. CONSTITUTION:The X rays from an X-ray source 22 are applied to a substrate 26 and the images of transmitted projection data are received by a camera 28 via a fluorescent plate 23 and an image-forming lens 27. The obtained projection data are A/D converted 32 and stored at a frame memory 33 and the line-shaped data through a reconfiguration section are extracted as projection data and are stored in a projection data memory 34. On the other hand, in a dropout part with a rotary angle where the substrate 26 and the X-ray source 22 are crossing, the substrate 26 is moved to the side of the fluorescent plate 23 for reducing it. The distance at this time is detected by an encoder 40 and stored and then is used for calculating the expansion rate of an image processing unit 37. With the projection data which are obtained by reduction along with the move of the substrate 26, the expansion rate is aligned by the unit 37 and stored in the projection data memory 34 as the data of the dropout part. After the projection data over a half periphery or an entire periphery is collected, reconfiguration calculation is made by the image processing unit 37 before displaying at a display 36 as a reconfiguration image.
