摘要： 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.

摘要： 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. The output signal from the CCD is sent to an external display unit via a cable extracted from the convex portion of the container through an FPC connector and an FPC provided on a surface opposite to the incident surface.

摘要： Images are to be satisfactorily continued even at joints of image regions.The surface of a fluorescent screen on which an X-ray image is to be formed is partitioned in the longitudinal direction of a slit, into image regions. From the image regions, image information is guided to CCD imaging elements by optical fiber bundles. Boundaries of the image regions are formed so as to be inclined with respect to the longitudinal direction of a slit.

摘要： 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.

摘要： 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.
