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： 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.
