The present invention relates to a mechanism that can be easily set up for a measurement object. FIG. 2 is a block diagram of a conventional high-speed X-ray CT scanner system. The high-speed X-ray CT scanner system greatly speeds up the scan time of a conventional X-ray CT scanner by adopting an electron beam control method of electrically turning on / off X-ray generation (1/60 to 1).
/ 2000 seconds). In a conventional high-speed X-ray CT system, as shown in FIG. 2, fan-shaped X-rays generated from a plurality of circumferentially arranged X-ray tubes 2 placed in an X-ray generator container 1 After the light exits from the container irradiation window 8 and passes through the object 9 to be measured, the light 7 is received by the detectors 4 arranged on the concentric circles of different diameters from the X-ray tube 2, converted into current signals, After being amplified by the main amplifier 11, it is sent as a voltage signal to the data recording device 15, and the data processing device 16 obtains a two-dimensional CT reconstruction image. The instructions for data recording and X-ray generation are performed by the measurement control device 14. [0004] In a conventional high-speed X-ray CT scanner system, it is impossible to measure an object to be connected due to its structure. Also, it is difficult to set a long measuring object. The present invention provides a high-speed X-ray CT scanner system which does not lower the resolution of the system and which can easily set the system not only for continuous measurement objects but also for long measurement objects. The purpose is to do. (First Means) A high-speed X-ray CT scanner system according to the present invention comprises: (A) an X-ray generating unit container; A plurality of X-ray tubes arranged on a circumference; (B) an X-ray generation control device; and (C) a container irradiation window for transmitting fan-shaped X-rays generated from the X-ray tube;
(D) X exiting the container irradiation window and penetrating the measurement object
A detector for inputting a line and converting the signal into an electric signal; and (E) a data recording device for inputting a signal from the detector and outputting the signal to a data processing device. ,
(G) An insulating gas is sealed in the X-ray generation part container divided and divided by the partition in the circumferential direction. That is, in the high-speed X-ray CT system according to the present invention, the X-ray generating unit container is divided into a plurality of parts by a partition wall in the circumferential direction, and discharge in a short path generated between the partition wall and the X-ray tube is prevented. In order to prevent this, an insulating gas is sealed in each of the divided and divided X-ray generator containers. FIG. 1 is a structural diagram of a high-speed X-ray CT system according to the present invention. The X-ray generating unit container 1 is divided into multiple parts (three in FIG. 1) by a partition wall 17 so that the measurement object 9 can be approached from the side, and after setting, it is positioned and fixed by bolts 19. Then, in order to prevent discharge in a short path newly generated in the partition wall 17 and the X-ray tube 2, an insulating gas 18 is filled instead of the conventional atmospheric atmosphere 20. ADVANTAGE OF THE INVENTION According to this invention, since an X-ray tube can be arrange | positioned close to a partition, resolution does not fall. Since the present invention is configured as described above, it has the following effects. (1) According to the present invention, it is possible to approach an object to be measured from a side. (2) For this reason, it is possible to measure a measurement object having a continuous length, which has been impossible in the related art, and to perform measurement with a conventional resolution.
