摘要： PURPOSE:To obtain a beautiful tomographic image by forming an opening part eccentrically to a large rotatable table, providing a small table opposite the opening part, and mounting a body to be inspected on the small table. CONSTITUTION:A small inspected body mode is selected with a table selection switch 47 and a rotary driving device 25 is driven through a mechanism controller 45 to rotate the large table 7 so that the position of the small table 17 is the position where the radiation beam width of radiation from a radiation generator 1 is minimum, thereby positioning the small table 17 at the closest position to a radiation generator 1. Then the rotary driving device 25 is fixed and the small body 21 to be inspected is mounted on the small table 17 so that the center of the body 21 to be inspected comes to the center of rotation of the small table 17.

摘要： PURPOSE:To widen a permeation image area by a method wherein a substance to be measured is rotated by a prescribed angle and made to traverse by a prescribed distance and collected data are rearranged to obtain permeation data. CONSTITUTION:A traverse table 31 and a rotary table 29 are set at a traverse position for each prescribed distance and at a prescribed angle of rotation respectively, and a substance 27 to be measured is set at a prescribed position. Next, a frame is moved vertically by the control of a vertical motion mechanism 43, and an X-ray emitted from an X-ray tube 23 and transmitted through the substance 27 to be measured is detected by a detector 25. X-ray permeation data of this scanner element 1 are collected by collecting element 9 and stored in a memory 11. The data in the memory 11 are stored as a cross-sectional image in a memory 17 through a preliminary processing element and a recon struction control element 15. Besides, the data are rearranged through a re arrangement control element 19 for sinogram and then stored in the memory 17. Then, a permeation image of the data in the memory 17 is displayed 21.

摘要： PURPOSE:To obtain a roentgenographic image with limited noise by a method wherein a planar light emitting means is irradiated with a radiation penetrating an object to be inspected and the radiation is converted into a quantity of electricity according to a quantity of light from the light emitting means to be outputted while the light emitting means is shielded from the radiation. CONSTITUTION:An X-ray beam 3 radiated from an X-ray tube 1 irradiates an object 9 to be inspected. When receiving the irradiation of the penetrating x-ray beam 3 obtained through the object 9 to be inspected, a scintillator 21 generates a visible light 23. An X-ray shielding body 25 is disposed between the scintillator 21 and an imaging optical system 29 to protect the optical system 29 or the like by shielding the beam 3. A visible light 23 generated with the scintillator 21 penetrates a shielding body 25 to be focused with the optical system 29. In other words, the visible light 23 generated at a point A is focused to a point B on a CCD image sensor 311. The visible light 23 thus focused is detected with a sensor 31 and a roentgenographic image is displayed on a display device 33. In addition, there is limited scattering of X rays in the scintillator 21 and higher resolutions of X rays penetrating the object 9 to be inspected is achieved.

摘要： PURPOSE:To gather calibration data and to increase the clearance at the time of the detachment of a body to be inspected by moving a moving frame on a rotary frame and positioning the reference phantom between an X-ray tube and a detector. CONSTITUTION:The moving frame 17 is moved linearly to a broken-line position along a couple of rails 16 of the rotary frame 15 and set so that a rotary sample base 21 is between the X-ray tube 18 and an X-ray detector 19. Then the reference phantom is mounted on the sample base 21 and set so that an X-ray beam 10 strikes on a specific position. Then, the X-ray tube 18 emits X rays and while the X rays are measured by the detector 19, the sample base 21 is rotated in the stop state of the frame 15 to gather the calibration data. Then they are inputted to a CPU and used as calibration data at the time of normal scanning. Then the reference phantom is detached, the frame 17 is returned to a full line position, and the gathering operation for the calibration data is completed. Thus, data on the normal body 20 to be inspected are gathered.

摘要： PURPOSE:To eliminate the influence of a crosstalk phenomenon and to improve the picture quality by correcting radiation projection data by a detector which has radiation detecting elements arranged according to information regarding scattered radiation among the radiation detecting elements, and outputting a tomographic image. CONSTITUTION:An X-ray beam 11 is projected on a body 17 to be inspected and the projection data is inputted to an X-ray detector 13. At this time, an X-ray source 12 and an X-ray detector 13 are rotated to project the X ray on the cross section of the body 17 to be inspected in respective directions. The X-ray detector 17 is constituting by arranging the X-ray detecting elements composed of scintillators and photoelectric converting elements and arranging collimators among the elements. At the time of its detection, the X-ray beam is transmitted through a collimator and enters an adjacent scintillator to cause a crosstalk phenomenon. A CPU 19, however, corrects an error in each radiation detecting element output due to the crosstalk to reconstitute an image. Thus, the influence of the crosstalk to reconstitute and image. thus, the influence of the crosstalk phenomenon is removed by the correction. so a high-resolution, excellent tomographic image is obtained.

摘要： PROBLEM TO BE SOLVED: To detect both foreign matter of metals and non-metals by irradiating the specimens with radiation without directly leaking primary scattering of radiation out of openings for carrying in and out the specimens. SOLUTION: An X-ray shield body 9 having openings 9a and 9b for carrying in and out specimens 2 surrounds X-ray shield bodies 8a to 8c, an upper conveyor 5, an X-ray tube 6, an X-ray sensor 7, etc. In this shield body space, most X-ray of the tube 6 irradiates specimens 2 by way of the slit 11a of the X-ray collimator 11 and transmits through the specimens 2, the belts on a horizontal plane, the slit 8a1 of the shield body 8a and goes in the sensor 7. On the other hand, the primary scattering X-ray 61 (the extended line between the irradiation sport of X-ray on the specimens 2 surface and pulley 10) partly generated during irradiating the specimens 2 irradiates the vicinity of lower end of upper fringe of the openings 9a and 9b to be secondary scattering X-ray and attenuates to 1 millionth of the tube 6 X-ray so that it clears the legal requirement X-ray leak level. By this, both of metal and non-metal foreign matters in the specimens 2 can be detected without direct leakage of radiation.
