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.
摘要翻译：本发明提供一种X射线断层成像装置，其中由CCD传感器（3c）等引起的图像劣化成分减少，以获得高品质的X射线图像。在断层成像之后，通过从存储在图像存储器中的图像数据中的特定数据线减去暗电流校正数据来消除暗电流噪声。接下来，基于在具有几乎均匀的强度分布的X射线束进入X射线成像装置3时获得的数据来准备灵敏度校正系数。然后将在暗电流校正之后获得的图像数据乘以灵敏度校正系数。结果，可以消除由于灵敏度变化等引起的噪声。

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.

摘要： A diagnostic/treatment instrument such as a handpiece equipped with a dental treatment tool, etc. is provided with a light radiating unit that can distinctively detect a dental lesion, to facilitate the treatment of the lesion. A light source for emitting light that can distinctively detect the lesion is mounted near the head of the handpiece to which a diagnostic/treatment tool can be attached. The light emitted from the light source illuminates an area forward of the diagnostic/treatment tool. Alternatively, the light source comprises a plurality of light-emitting devices which are arranged around the periphery of the forward end of the handpiece head in such a manner as to encircle the diagnostic/treatment tool, and radiates light to illuminate the area forward of the diagnostic/treatment tool. When an oral cavity is illuminated with the light, a clinician can observe reflected fluorescent light by using a filtering function that passes the fluorescent light, and thus the clinician can perform the treatment while checking the lesion.
