PURPOSE:To obtain an image having no halation by giving a rotary book X-ray absorptivity regarding the columnar body and entering only X-ray magnetic flux transmitted through a body to be inspected and rolls into a fluorescent light multiplier tube. CONSTITUTION:For inspection, the cylindrical body 15 to be inspected is placed on a support 16 and a table 26 is moved by a driving mechanism to position an inspection target part in the center of a visual field; and the body to be inspected and rolls 21 and 22 are set occupying the whole visual field of the fluorescent-light multiplier tube and then X-ray luminous flux is projected on an X-ray tube device 11. The X-ray flux transmitted through the body to be inspected is made incident on the input surface of the fluorescent-light multiplier tube 12 to form a visible image on the output surface of the fluorescent-light multiplier tube and this visible image is converted by a TV camera 14 into a video signal, which is outputted to a display device 17 outside a protection wall. In this case, the rolls 21 and 22 which constitute the support 16 are rotated by a motor and fluoroscopic images of the object body 15 in many directions are displayed on the display device 17. |
