Abstract: A phosphor, an optical fiber plate containing lead particles, a CCD, and an X-ray shielding member consisting of copper tungsten are sequentially stacked on a substrate from an X-ray incident surface side and sealed in a container made of a light-shielding synthetic resin. The substrate has projecting portions projecting toward the direction of X-ray incident along three sides of the X-ray incident surface. Each of these projecting portions has an overhang portion projecting toward the optical fiber plate. The overhang portions are close to or in contact with corresponding side surfaces of the optical fiber plate so that the optical fiber plate is fixed at a predetermined position. The container has, in the inner surface, convex portions corresponding to the projecting portions, so the substrate is fixed in the container.

Abstract: An X-ray detecting element detects an image produced by X-ray irradiation. An apparatus case capable of being inserted into a mouth has an X-ray irradiation face having different dimensions in two directions perpendicular to each other, and houses the X-ray detecting element. A cable is connected to the apparatus case to transmit a signal from the X-ray detecting element to the outside of the apparatus case. The cable is drawn out from the apparatus case in a direction which is parallel with the X-ray irradiation face and perpendicular to the longitudinal direction of the X-ray irradiation face. According to this configuration, the cable does not obstruct the imaging operation in a course of imaging teeth in a mouth, particularly a molar portion. Therefore, an imaging operation can be easily conducted without giving the subject an unpleasant feeling.

Abstract: The present invention provides an X-ray tomographic imaging apparatus, wherein image degrading components caused by a CCD sensor (3c) or the like are reduced so as to obtain high-quality X-ray images. After tomographic imaging, dark current noise is eliminated by subtracting dark current correction data from a specific line of data among image data stored in an image memory. Next, sensitivity correction coefficients are prepared on the basis of data obtained when an X-ray beam having nearly uniform intensity distribution enters an X-ray imaging device 3. The image data obtained after dark current correction is then multiplied by the sensitivity correction coefficients. As a result, noise due to sensitivity variations or the like can be eliminated.

Abstract: The present invention provides a panoramic imaging apparatus capable of obtaining a clear tomographic image even when the rotation speed of a swivel member changes. The clock for driving an FFT CCD device in accordance with the TDI method is set on the basis of the angular speed .omega. of the arm detected by a tachogenerator and a function value f (.theta.) which responds to the rotation angle .theta. of the swivel member detected by an angle detector and used to determine a tomographic orbit. The angle detector is provided with a cam having a shape having been set in accordance with the relationship between the rotation angle .theta. and the film feeding speed at the time of performing X-ray panoramic imaging by using photographic films. The signal of the angular speed .omega. and the signal of the function value f (.theta.) corresponding to the angle .theta. are added by an analog multiplier, and subjected to frequency modulation by a V/F converter to create a TDI clock.

Abstract: The solid state image sensor comprises a chip in a package. A image sensor is formed in the chip. The package has a package main body, a light receiving glass plate fixed to the package main body, and a buffer member arranged between the package main body and light receiving glass plate. The buffer member is fixed to the light receiving glass plate and to the package main body. The thermal expansion coefficient of the buffer member is substantially equal to that of the light receiving glass plate, so that the light receiving plate is fixed to the package main body even though the temperature of the imaging device changes. Therefore, the adhesion between the package main body and the light receiving glass plate and the airtightness in the package are maintained.

Abstract: A medical X-ray tomographing apparatus, wherein the output end surfaces of a plurality of optical fiber bundles are optically coupled to the image pickup surfaces of vertically long solid-state image pickup devices, such as one-dimensional image sensors, and the input end surfaces of a plurality of the optical fiber bundles having a vertically long cross-sectional shape being identical to that of the output end surfaces thereof are optically coupled individually to a plurality of vertically long divisions obtained by dividing the fluorescent surface of a scintillator in the width direction thereof. With this apparatus, it is not necessary to significantly contract the size of the image on the fluorescent surface, thereby remarkably reducing the number of the solid-state image pickup devices and the number of the divisions of the fluorescent surface.
