    摘要： It is an object of the present invention to provide a transmission imager which can produce a transmission image from two or more different view points with the use of a simpler arrangement. The transmission imager according to the present invention is provided having a radiation source 2 for radiating radioactive rays from its target 2a, a radiation detector, and a specimen table provided between the target 2 and the radiation detector for having a specimen to be examined placed thereon, wherein the radiation detector is arranged with its detecting surface at the center P extending substantially at a right angle to a reference axis L1 or L2 which extends from the center P to the target 2a. In particular, the transmission imager is characterized in that the radiation detector is a combination of two, first and second, radiation detectors 3 and 4. The first radiation detector 3 is arranged to be moved to and from the target 2a by the action of a driving mechanism and thus positioned further from the target 2a than the second radiation detector 4. The radiation source 2 is specifically arranged in relation to the two, first and second, radiation detectors 3 and 4 so that its target 2a comes at an angle to face a cathode 2b which is disposed closer to the second radiation detector 4.

    摘要： An image processing method and device for quick supplement. Defective pixels (Da, Db) are detected by the difference between the imaging light in irradiation and that in nonirradiation in advance. The sound pixels surrounding the defective pixels (Da, Db) are related to the defective pixels (Da, Db) and stored in a supplement list as supplement pixels (R1 to R8, R1 to R16). An average pixel density of information on the supplement pixels (R1 to R8, R1 to R16) is determined referring to the supplement list when an image is displayed, and the average pixel density is indicated as the values of the defective pixels (Da, Db) corresponding to the supplement pixels (R1 to R8, R1 to R 16). If the difference between the imaging light in irradiation and that in nonirradiation is below a predetermined threshold, the pixels (Da, Db) are judged to be defective.
